I am still keeping most of this "compartmentalized" as i am having trouble accepting the passing of our three year old Aussie.

She was healthy up to Friday last week when i thought she was constipated for a couple days, so when she still was constipated the next day (Saturday) i took her to a new vet that was open on Saturdays (It was Saturday afternoon at 4:30pm), one that is open 24 hrs for emergencies, as the normal veterinarian we went to around here is more of a clinic.

I explained that she was not eating, and though her back end was uncharacteristically now becoming regularly messy, never did i see any poops drop, though i did see her strain several times. They took X-Rays and believed everything should be fine, just to watch her, and they also strongly recommended we get her on Heartgard+ 272mcg Chewable and NexGard Chewable 60.1 - 121 lb (She was 62.3 lbs). She never was on those before (we moved here to Florida from Colorado Springs, where both ticks and mosquitoes were rare).

The 04/25 invoice shows:
Examination General
Total Health With UA 4Dx O&P G
Radiograph and Interpretation
Heartgard+ 272mcg Chewable
NexGard Chewable 60.1-121lb

I brought her home and we gave her a few meals of pumpkin, on Sunday and Monday she was pooping just fine.

Tuesday, in the early afternoon i gave her the two medicines.

Tuesday nite she was drinking water in the extreme. Where she normally would have a doggy bowl that would last her easily throughout the night, in the evening alone she literally drank down more than three, perhaps four, gallons. Though i did not observe it, my wife stated that she was peeing around the house and she could hear "sloshing" in her stomach.

On Wednesday morning i took her back in to the new vet, though she saw a different doctor, as they traded shifts. I explained that we were alarmed by the severe increase in drinking. I was told that the blood and fecal work from the visit a few days ago came back fine. She was still able to walk on her own and jump into and out of the car, though with much less energy. They did multiple tests, and took two more x-rays. She was negative for diabetes, and thought they had indications of pancreatitis. They suggested that she could be "hospitalized" there or we could take her home and self-medicate with several prescriptions, and recommended a very bland diet (boiled chicken and rice). I asked if there was any significant chance that i would be risking her life if i chose to treat her at home, the vet indicated she did not think so, stating that the level of severity was about 5 on a 1 to 10 point scale, and had me schedule a follow-up visit for the next day.

The 04/29 Invoice Shows:
Recheck - FollowUp Examination
Radiograph - 2 views
Pancreatitis Test
Blood Glucose Test Alpha Trak
Cerenia 51-75lbs
Tramadol 50mg Tablets
Carfate Tablets
Omeprazole Capsule 20mg
Cerenia Tablets 60mg-4pack

Once home she was very lethargic; though normally very active, she seemed to not want to move around at all. I presumed they must have given her some medication and that she needed rest.

She was still drinking a lot of water that nite and threw up some of the water, and whimpered throughout the nite. Though we had a follow-up visit scheduled for 2:40pm Thursday, i drove her in to the new vet in the morning. I had to carry her into the car. Breathing was labored and she would occasionally whimper on the ride in.

Once i got her to the vet, the same doctor she saw on Saturday, he carried her in with his arms under her chest and belly. Though it was raining, it seemed to me she was peeing water. He took her into the back and then almost immediately he came out and asked me for permission to do CPR as she stopped breathing. She couldn't be brought back.

Though they offered to send her out to be examined, i declined as that wouldn't bring her back and i was stunned; i couldn't reconcile how she could have passed away. He asked me if it were possible that she could have gotten into any poisons but there is nothing - we have always been very careful to keep anything out of reach since an early episode with a bag of Dove chocolates a couple years ago. We laid her to rest.

I am not so much looking to blame, as much to understand.The only variables other than what she might have had going on internally, if anything, during the second visit to the vet were the HeartGard and NexGard chewables, and the canned pumpkin. Because the mosquito and flea medicines are so widely used, i doubt the connection, but i still must wonder; they were absolutely the only variable other than if some strange condition existed or anything they might have given to her that i was not aware of.

Can anyone, especially a professional, provide inout as to what might be related to the extreme thirst and passing of our dog? As every one in the past has been, she is a family member; I am still blaming myself for not choosing to "hospitalize" her. I would appreciate some help, please-

I'm so sorry. Sometimes things just happen, but personally I wouldn't use a vet who would prescribe a bunch of chemicals for a dog that had just had a digestive problem. Yes, those things are widely used, but yes, just like human meds, there are always some who have reactions.

I'm very sorry this happened to you and your pet. Please don't blame yourself.

Some breeds of dogs, such as collies, Australian Shepherds, Shelties, and other herding breeds more commonly have a gene mutation (MDR1) that makes them more susceptible to serious side effects from ivermectin (and other drugs), which is a main ingredient in Heartgard. Basically, their bodies can't flush that protein from the brain like it's supposed to, and they can experience lack of appetite, vomiting, diarrhea, lethargy, motor impairment, and trouble breathing, which if left untreated can lead to death. You can read more about that here: MDR1 FAQs - Australian Shepherd Health & Genetics Institute

I have no idea if that's what happened to your dog (I'm no vet), but I have a Collie/Australian Shepherd mix so I became aware of the mutation.

I have no idea what the initial problem was caused by that first caused you to bring you dog to the vet. Could have been a simple digestive upset that fixed itself. But the events after giving the meds makes me think of the MDR1 mutation. The only way to know for sure is to do an autopsy or have her DNA tested.

Most ethical breeders who breed herding dogs generally susceptible to the mutation test their dogs for it, as well. I would most definitely alert your breeder or asker him/her about it. They would want to know.

I'm so sorry about your pup.

I thought about the MDR1 thing when I was reading this too, but it doesn't really sound like a typical case of ivermectin poisoning, does it? No seizures or neurological issues. I agree that I would feel weird giving the med to a dog that's already not feeling well, but I think a lot of emergency vets tend to "seize the moment" as they see a lot of dogs suffer with heartworm. Plus, fecal issues can be caused by being overdue for deworming.

Pyometra can cause extreme thirst and closed pyometra can be really sneaky. So can kidney and pancreas issues of various types and causes. I think it may be impossible to say what caused this without the post-mortem exam, as there are a lot of conditions that don't show up well on external scans.

Please be kind to yourself and your vets about this - the majority of the time, unless there's a blockage, an upset stomach goes away uneventfully after a few days of bland feeding, and you did have your vets scan for a block as well as test for the stereotypical cause of unusual thirst, diabetes. You weren't to know that this wasn't a typical case.
