Just be warned that if you order this item it does NOT come in th e pictured labeled and sealed bottle, it arrives in a personalized but UNSEALED prescription bottle. For that reason I will be discarding the 30 tablets I received and won't order the product again.

Impossible to administer

I have used a finger cot to get the pill far back in poor Theo's mouth. I've used the pill dispenser. I've coated it in treat-food. I've tried everything: he vomits it up with cups and cups of thick foam. It isn't tolerated AT ALL.

Probably good . . .

I ordered these off the recommendation of the 3rd vet I took Mojo to for the head wagging, sneezing, neck scratching that tortured him for many months. Nothing was helping these issues. The 4th vet, last week, discovered that Mojo had some kind of bug debris next to his right eardrum!! Vetadryl would not have helped that.

Picky Puppy

My pup won't take this on it's own but if we ball it up in a small amount of cheese, he will take it. It must not taste very good because he will sometimes manage to eat just the cheese and spit out the pill ( which I find later on the carpet.) I am still using these because they do work and have stopped him from chewing/licking his feet.

Do Not Buy!!!

My dog takes beef flavored medicine “treats” so I bought her these and she WILL NOT eat them. Ive tried everything from pill pockets, to mashing it and putting in wet food, to pretending like I was going to eat it. She spits it out or doesnt eat it at all. These need better flavoring or something!

Not good with cats

This should be available as an unflavored or capsule for cats. My cat drools like a St Bernard even if I get it right on the back of his tongue. He has started to run whenever I get near him for fear of the bitter pill. I’ll be looking elsewhere.

Not a good choice for cats

Mr. Bojangles has allergies and we wanted to try something new. The store bought version had to be cut and thus he got the taste in his mouth which led to severe mouth foaming and drooling. These are supposed to be chew-able. They aren't. Once again the taste of the medicine far out weighs the "chicken" flavor. Unless you are an expert at getting pills in your cat without getting them anywhere near his tongue or cheeks, you will have to deal with a foaming and drooling miserable cat for 5-10 minutes. The 3 stars are because they actually worked once all of the drama was over. We are definitely looking for something a lot more user friendly! Chewy, as always, is the best!

Best ever product

My puppy was a habitual licker due to allergies. No more licking since we started this medication
