Something strange has happened. Our 6 year old boy seems to have suddenly had a reaction to his flea stuff, Effipro, which he has had for the past year.
This is a new batch we picked up from the vet 2 months ago. The first time, i thought it was a reaction to his vaccination, but the same thing has happened when i've given him his effipro this month. Basically, the area where I apply the liquid ended up becoming a bald patch very quickly! He know has two small bald patches where i have applied them over the past months. Needless to say I'm not going to apply anymore next month.
I will be taking him to the vet to see what he says, but just wondering if anyone has had any experience of this with flea treatments?
