My puppy Sam is almost over his kennel cough and he finishes his antibiotics today! So tomorrow he's going back to the vet for another checkup. I've been asking them what to use to prevent fleas and ticks and they keep telling me to wait since he's still sick. He hasn't even had his 2nd round of shots yet b/c he's been on antibiotics since I got him (May 18). I looked up Revolution and it seems to treat and prevent A LOT!! I also looked up Frontline Plus. Can anyone help me decide which is better to use? I know a lot of people on here seem to use Frontline, but it says Revolution also prevents heartworm so it's like killing 2 birds with 1 stone. What should I do?
