My much loved Neapolitan Mastiff is now 3 years old, but he very nearly didn't make it to his 3rd birthday due to fish oil tablets, this is his story.

Neo is a beautiful dog, a much loved member of our family. His favorite activities include stealing my shoes, long walks, socializing with other dogs at the park, sitting under the mulberry tree eagerly awaiting ripe mulberries to drop off for a snack, car drives and relaxing on the couch with his head on my lap.

His dislikes include, bath time, swimming, cats, vacuum cleaners, lawn mowers and being roused on when naughty (when roused on he gets the sulks and goes and sits in another room until I come and apologize lol).

He's very spoiled, I make his own food, he has a very balanced diet, lots of fresh meats, fresh fruits and fresh veggies, he's never spent a night outdoors in his life.

A few months ago I noticed he was seeming a little lame on his back legs, I took him to the local vet, who examined him, couldn't see anything wrong, said it was "probably just arthritis". I asked for a referral to an Orthopaedic specialist to make sure.

The specialist couldn't see anything obviously wrong with him, and said it's most likely arthritis with him being such a large dog, and we were prescribed with Rimadyl for the pain and inflammation.

Both the vet and the specialist said I should also supplement him with Fish Oil and Glucosamine. I mentioned Neo was already taking fish oil and had been all his life as the breeder said they were great for healthy joints and a beautiful coat, with regards to the fish oil I told them he was having 8 capsules a day (keeping in mind he's an 80kg dog, 4 each meal), both vets said this was a good amount.

Neo's condition deteriorated gradually over the next few weeks, he had so much trouble standing up and sitting down, he seemed to be in pain. I went back to the specialist who gave Neo a prescription for Tramadol in addition to the Rimadyl. He said if there was no improvement he would need to do exploratory surgery and take x-rays and biopsies etc. Unfortunately as he is a specialist he was very busy with emergency cases so this couldn't be for another week.

The next day Neo's condition had worsened, he wasn't himself, he was puffing without exercise, he was pretty much paralyzed in the back legs now, i had to help him up a lot of the time and he was yelping in agony when touched and even randomly yelping when resting.

I took him to the local vet and demanded x-rays of his legs, hips and spine be done, they found some spondylosis (they said this is like arthritis on his spine), and deduced this was the cause of his pain. They said the rest of his life would be about pain management now, and was prescribed some heavy pain killers, Valium and more Rimadyl.

I didn't accept this diagnosis and took him to see yet another vet for a second opinion. This vet was great, he actually seemed to care about Neo. I asked for a full ultrasound to be done on Neo to make sure he didn't have any tumours, as this vet said the amount of pain he was in didn't seem to correlate to the small amount of spondylosis on his spine.

A nervous day spent awaiting the results and thankfully the ultrasound came back clear. We discussed the options available including low dose short term only steroids and also stem cell therapy, I decided to think about both, still not certain in my mind it was arthritis. We also discussed supplements such as glucosamine, fish oil, Sasha's blend (green lipped mussel) and he even suggested milk thistle for Neo's liver if he took the steroids.

After our visit to this vet I also took Neo to a naturopath, the naturopath said fish oil was great for dogs, also glucosamine, he said the human stuff was better than the pet stuff and cheaper. He also gave us some herbal treatments for pain management.

Still not content (the amount of pain he was in seemed enormous given that he was on heavy pain killers), he also seemed to be in pain everywhere, not just his back legs or back, it just didn't make sense to me, and I wasn't ready to give up on Neo and resign him to a life of pain management and horrible drugs until i had a definitive diagnosis, not a "maybe" or "probably".

So i got on the internet and spent several days and sleepless nights researching causes of extreme pain and lameness, when finally I came across several articles about "vitamin E deficiency", and then the more researched the more everything fit!

The articles said it was very rare in dogs (it's apparently seen more often in cats that eat tinned tuna) and extremely hard to diagnose, but symptoms included:
- severe pain
- hyper sensitivity to pain
- lack of muscle tone
- lameness
- paralysis
- skeletal problems
- muscle weakness
- leg/feet swelling
- edemas
- weight loss (although no loss of appetite)
- cataracts
- premature aging

I could tick pretty much every box except the cataracts, Neo had 2 edemas earlier in the year in both his back legs, at the time the vets couldn't explain them, biopsies were negative for nasties, they were just "inflammatory fluid", I was told they were most likely bites, although they appeared to come from the "inside" of the leg, ie there was never any "bite" mark, no damage to the external skin, I had no reason to think these were related in any way to his "arthritis" which started months later.

As for the premature aging his face was also going grey already, which I thought was unusual for a 3 year old dog, which was one of the reasons I asked the vets to ultrasound his organs for tumors.

The good news is, as soon as I read these articles and all the puzzle pieces just fell into place I drove straight to the 24/7 chemist, bought vitamin E capsules (the natural vitamin E) and started him on them immediately and threw out the fish oil tablets. Within 24 hours he was able to get himself up without any help, later the next day he was up and walking around again albeit stiffly and limping, within 2 days he was barely limping and all the yelping had stopped, he was also able to stand up and sit down easily again.

After 3 days the limp was gone and his pain was almost gone, i started reducing his Rimadyl and pain killers gradually and after only 1 week he was running, jumping, playing, back to his old regular cheeky self again, and he was free of all medications!!! :)

Even with the rain this week and colder weather he hasn't shown any signs of "arthritis", he's like a puppy (albeit a giant one) again! :) I have my boy back!

2 weeks ago a guy from work told me about his 10 year old Maltese, who was collapsing, lame, had cataracts, he was being tested for "Cushing's disease", he'd already being tested for spleen cancer and diabetes. I curiously asked him if he fed his boy fish oil tablets, he said yes he was fed 2 per meal for his arthritis, had done so for years.
I suggested 4 fish oil tablets a day for a little dog like that might be a worry, and suggested he stop the fish oil and get the vet to test for vitamin E deficiency instead, and sure enough the test was positive, he had acute vitamin e deficiency. Within a week his boy was cured too.

So this got me wondering, if a guy i work with also has this problem with his puppy, just how many other peoples dogs is this happening to? Are vets diagnosing any general unexplained pain as just blanket "arthritis"? Are dogs being put to sleep because they have "chronic arthritis" when all they need is a $5 bottle of vitamins for a complete cure? Are we killing our best friends with love (aka fish oil/omega 3)?

I decided to write this post in the hope that it will save a dogs life. This information is really hard to find and studies are only just starting to come out about the dangers of over supplementing fish oils without balancing them with vitamin E, and most of those are human studies, and humans generally get much more vitamin e in their diets than dogs do. Vets don't seem to be aware of it, in fact, they seem to be promoting the use of fish oil.

As a giant breed Neo was told by his breeders to take fish oil as a preventative and for a nice coat, and his vets all agreed, yet this almost killed him. Fish oil isn't as safe as vitamin sellers would have people believe.

Below I'll go into some more detail about what my research turned up for those who are interested. I'm not a vet or a scientist so please do your own research and speak to a decent vet about it who is aware of vitamin E deficiency before supplementing your dog with anything!

From what I've read vitamin E deficiency can be caused by any of the following essential fatty acid containing products, but especially combinations of them:

- Fish Oil supplements
- Flaxseed Oil supplements
- Other omega fatty acid supplements EPA/DHA/OMEGA3 etc
- Frozen fish
- Canned fish
- Green Lipped Mussel products (Sasha's Blend, Technyflex, Glyde etc)
- Some dogs have digestive problems which prevent them from digesting fats (and consequentially vitamin e) properly.
- Diet (most dogs don't eat vitamin e rich foods like nuts, wheatgerm, plant oils etc)

(Note: Apparently fresh raw fish is ok because it contains vitamin E naturally, but freezing, cooking, canning, processing it kills the viatmin E but leaves the omega 3's intact.)

You can avoid vitamin E deficiency in your dogs by simply supplementing them with SMALL amounts of vitamin e if you give them fish oil or buy a decent brand of fish oil that has enough vitamin E added to offset the depletion (I understand it's as little as 4 iu - 10 iu of natural vitamin E per 1000 mg of fish oil is all that's required to prevent the fish oil from depleting a dog's vitamin E levels). But the amount you need to give your dog will obviously depend on how big the dog is, and how much essential fatty acid containing products and foods with vitamin E they already consume as part of their diet.

So don't run out and buy 1000 iu vitamin e tablets and give them to your dogs! Too much fish oils (essential fatty acids) deplete the body of vitamin E, but too much vitamin E will apparently increase the dog's requirements for vitamin A, vitamin K and vitamin D! (It's quite a balancing act, which is why supplements can be dangerous!) Also vitamin E in mega doses like 1000 iu's can cause bleeding/hemorrhaging because it thins the blood.

Below is a quote from the website (http://mydogyogi.wordpress.com/) i found the most useful, and the one that saved my Neo's life:

"When giving fish oil (to your dog) on a regular basis extra vitamin E, an important fat-soluble vitamin and antioxidant, is typically needed. Fish oil oxidizes easily and the (dog's) body will use up its stores of vitamin E when processing fish oil. Therefore sufficient vitamin E is required in the diet to prevent a vitamin E deficiency in your dog.

Most fish oil supplements contain additional vitamin E, though this is typically only enough to preserve the product and not a significant source for the body to use. It is better to supplement natural vitamin E instead of synthetic, so when buying vitamin E look closely at the label. Natural vitamin E is listed as d-alpha-tocopherol and synthetic vitamin E is listed as dl-alpha-tocopherol. One little “L” makes a big difference is how effectively the (dog's) body can use it.

I encourage you to work together with your veterinarian to determine if a fish oil supplement is okay for your dog and to find out dosage information for both the fish oil and vitamin E."

I hope the information I've collected above proves useful for some other dogs out there, and their owners. The 3 thing I've learned from all this are:
- Supplements can be dangerous, even "SAFE" ones.
- Vets are human, they're not always right and they can't be expected to know everything, as an owner you know your pet better than anyone else.
- Never give up, seek second opinions, do your own research.

Rimadyl can be dangerous, yes, but her dog was already in pain and had muscular problems before even going on it. Those problems are now gone, it wasn't the rimadyl that caused them (not saying the fish oil did ether).

I give my dog two capsules of fish oil and two capsules of vitamin E (feed her twice a day), but like you mentioned I only heard about fish oil originally, but after spending time on a few forums and reading a lot it's clear that vitamin E is necessary when supplementing fish oil.

It's a shame that google is a better vet than most out there.

To piggyback on the Rimadyl thing--when Loki was sick and in pain, they put him on Rimadyl...and two days later he lost all control of his bladder function. He would literally leak uring all over the place. He had a lot of stuff going on, but it was very coincidental to me that he got that symptom after the Rimadyl. It bothered me so much that when the tried to get me to put Gracie on it, I refused--just in case.

And to the OP--I think you have to be careful no matter what supplement you use and always talk to your vet first.

That amount of fish oil sounds outrageous to me, when DH & I took the stuff I only took 2 a day and I weigh more than Neo (130#). Were these vets even listening when you told them 8 caps a day?

BTW, DH & I stopped taking fish oil because it raised our LDL (bad) cholesterol signifigantly even tho' we had gone one a strict low fat diet. Once we quit those 2 caps a day our LDL cholesterol went down to the low 90s.

Thank you to the OP for sharing. What a well-written and balanced post. All of us have to research and think about what we put into our dog's bodies and we all have to remember that every "body" handles things a little differently.

I am glad your dog is on the mend and am impressed by your diligence in advocating for his care.

As for rimadyl, again, all of us have to balance the risks and the benefits and consider what is best for our individual dog(s). I had a lovely dog who was on rimadyl, tramadol, and amantadine (plus fish oil and cosequin) for 3 years. High risk? Sure. But she had no quality of life without it. All situations are different and all of us have to consider our very specific circumstances when we make treatment decisions.

Find a vet you trust. Learn all that you can. Adjust as your dog and situation requires. Keep learning.

Which is weird...no clue why it's being quoted all over now.

I have GSDs, who are not small. They get two capsules a day, that's it. Eight is just ridiculous

I think it was a bs post. Anyone that thinks a balanced diet for a dog with plently of fuits and veggies isn't playing with a full deck. They are called carnivors for a reason.

My dogs eat kibble three times a day, then get veggie snacks between meals.

A vet once pointed out that when a carnivore kills a herbivore, the first thing it does it rip the stomach open and eat the intestines, absorbing the vitamins and nutrition from the veggies it's been eating. He said they can't get too many veggies to supplement their diet.

A good dog food is going to have the vitamin and mineral content they need. They don't have the teeth or system to break down vagetables. They have very short intestines compared to humans, which is why they can eat raw meat and not get sick. Plant matter takes much longer to break down. That's why when grass goes in, grass comes out. I can't believe they are getting any nutritional value from it. I can believe that carnivores in the wild can get nutrition from partially digested plant matter from the stomach of a fresh kill.

Dogs evolved alongside humans eating our scraps, which included vegetable matter. They've been eating those scraps for thousands of years and I believe they get more nutritional value out of them than wolves do. Also, dogs are omnivores. And the idea that dogs never get sick from raw meat is laughable, my dog lost weight no matter how much meat I threw at her and I had to give it up.

That aside, I only give Roxie one fish oil tablet maybe twice a month at the very most and always add an egg to balance it out.

Except they don't :/. They go for the organs first---liver, kidney, etc. Rich and nutritious. I haven't had the opportunity to see what's left after a canine is done with an animal, but cats usually leave the stomach and intestines of whatever critter they got. The only thing left is a little pile of rabbit intestines. . .and the feet :p. Dogs can usually handle processed veggies (pureed, cooked, etc.) but if you give them whole raw veggies, you'll usually see it come out pretty much the same way it went in.

Dogs are bred to be dogs but I do not believe their basic anatomy has evolved. If you bred humans to be very short, very blond and very heavy boned, they would still be human and have the same system. Microevolution can happen fairly quickly but macroevolution is a different matter.
