I've been reading about comfortis and I really want to try it! The only problem is, is that cuddles is only 3.25 lbs at 6mths. and I read that it was only for dogs 5-10lbs. I was thinking about splitting the pill. Right now the vet just put her on frontline plus. I'm also giving her one brewer's yeast and garlic tablet a day. I really want to try comfortis but I don't want to have a large vet bill later if she gets sick. If anyone's tried comfortis for their puppy or dog under 5 lbs please let me know the results. thank you!
