I usually just freeze peanut butter in them. Or you could freeze some canned food mixed with kibble or really any number of things so long as they are ok for a dog to eat. For us though, the trick is to freeze it because it makes it take much longer to get the food out and it's less messy.
I mix a small bit (and I mean small) of pb in warm water and add in the food... when it is kinda mushy, I stuff it in the kong and freeze it. Seriously though... light on the peanut butter, it's really just to flavor the water, lol.
Like kafka said, freezing it is less messy normally, and keeps them busy longer. Though I would venture to say freezing it and giving it to a fluffy faced poodle could end up kinda messy. I freeze my poodle's but he has a clean (shaven) face and feet.
I used pb for one dog, I think I used it too much of it for one dog because POOP! I tend to use The Honest Kitchen....my dogs love the stuff and it freezes nicely in Kongs. If we are going to be gone, I mix THK and some kibble for their dinner. I've tried yogurt as well. Mine eat anything that doesn't eat them first, so...
I use Peanut Butter with Treats frozen in it. I also use:
Frozen yogurt and Bananas
Frozen yogurt and treats
Frozen Chicken Broth
Spray Cheese Frozen
Spray cheese and treats
Frozen water and treats
steak scraps and Cream Cheese (Not often)
That's all I can think of for now....
EDIT: I also freeze kibble (whatever brand you feed your dog) with either yogurt, water, chicken broth, or peanut butter.
I usually put some dry kibble in there and then "seal" it over with wet food, then put it in the freezer. He really loves that. Especially since I've been getting the Weruva canned food, which is like shredded chicken, he REALLY loves the Kong then.
I also buy plain no fat yogurt, put it in there, and freeze, but sometimes this can be kind of messy. Just because he often gets bored with just yogurt and will let the Kong sit on the floor and then it starts melting out, LOL. But if your dog eats it all at once, this will work much better.
Jackson never liked peanut butter so I only tried it once and he wouldn't TOUCH it and it was a MESS cleaning it out. So I never tried the PB thing again, plus most of them are pretty high in fat, and it wouldn't be my first choice of treat to give often.
I used to put cheese in there sometimes too and freeze it. Or shove some treats in there and again, seal it with wet food.
Anything really can go in there so long as it's healthy and edible for the dogs.
I fill it to the brim but of course, you should adjust your feeding depending on your dog's body condition. If the dog gains weight, just decrease food/treats etc. accordingly. If they're at an ideal weight now and you want to add more treats (like in the Kong) just slightly decrease the amount of normal food you feed. Pretty simple.
Is it okay for dogs to eat this? Dakota hasn't been eating her soft or hard dog food lately even if she hasn't had any treats through the day. i tried sprinkling Parmesan cheese on it and I've never seen her so interested in eating, she loves that stinky cheese!
Okay, so a couple of you know my dog Killian has quite a few allergies. He's allergic to grains, chicken and potatoes.
So, after doing a bit of research and asking around, I found zignature. They make their food with zero chicken and potatoes, and have three grain free choices.
Let's limit this thread to links and advice - especially for those of us who want to explore the possibilities of feeding raw. Let's start with the assumption that we all want whats best for our dogs and look at this as a possible option.

I wasn't sure where to post this but if it's in the wrong place, I'm sure somebody will rectify it. For a while, the customer service at Chewy was incredible. However, people must have taken advantage of that and now, it's really started to go downhill. Now, if something is delivered...
