Be aware that your dog/cat could be allergic to Frontline.
My Vet advised me to use Frontline as flea and tick protection for my collie so I started using it and applied the Frontline spot on at the subscribed doses at the subscribed times. Within weeks by dog had a sore rear right paw, one of his toes was bleeding and he was limping.
I visited the vet and he gave me a cream and told me to keep his paw dry and clean, after a while it got a bit better until a month later as his paw was raw again, I visited the vet and I was told the same again, I did exactly what I was told and again it heelded again until a month later and it happened again, went back to the vet who told me this could be chronic and I may have to consider an amputation of the affected toe.
As I thought that to be ridiculous, I did a lot of internet research and I watched my dog much closer and I found that as soon as I applied the frontline spot-on he started scratching his neck at the same spot and soon after that he started chewing that paw as now his paw was itching from the frontline spot on , I also noted that he really did not wanted the Frontline spot on applied and ran away as soon as I had the packaging in my hand.
Conclusion; I stopped using Frontline spot-on immediately, his paw healed within weeks and the issue has never returned again.
