I have used Frontline Plus on my dog since he was three months old and in my opinion worked well without problems. But my vet convinced me of using Comfortis which I just changed Nigel to.Originally Posted By: FredIf I remember correctly, you can't use these products on puppies less than 6 mos old. What do you do for them?
Our vet had us freaking about this also as we have ferrets. The dog would have to LAY ON TOP OF THE CAT in order for the cat to be effected by this. Unless of course the cat is sensitive anyway to chemicals.Quote:If you put it on your dog and it comes in close contact with your cat the cat could die.
