Dog likes it

Too soon to tell because Paco who is four pounds, only took one dose. He ate it with no problem and didn't have any side effects.

I like this but I am not sure if this a heartworm pill only, or it q combination of heartworm and flea medicine too.

Better GI tolerance

My 5 pound dog kept vomiting the lowest dose of another heart worm med. this dose is much lower and he tolerates it really well and loves the taste.

Taste good

My finicky little 6 lb Yorkie likes the taste. She normally smells a chewable then licks it if it smells good and if it passes the lick test she eats it.

Chewy is Best!

You couldn’t ask for a more efficient company then Chewy! I had to call to check on my order. The rep told me I had not actually placed the order and offered to order for me while on phone. Quick and easy!

Doggy Ate the Meds with No Issue

When my vet prescribed this medicine for my 6 lb Maltese, she noted that my dog may not like the smell or taste but luckily that wasn't the case. My dog chomps it down like it's any other treat. I do notice that my dog is a little fatigued a day or two after she takes it. Other than that, no other alarming side effects. Given she doesn't take any other meds, unsure if I would buy this again because I don't like my dog being fatigued by this medication on a monthly basis.
