Q. Can I put frontline.on a weak dog? Ticks are a bit much on him.afraid it gets worse while he is catching back his strength.
A. I would hesitate to put Frontline on a dog that is already showing signs of weakness. If he is infested, I would be more inclined to give him a bath with flea and tick shampoo and manually remove all the ticks and give him some time to recover somewhat before applying Frontline. If the ticks are a problem in your area, the Frontline may not be adequate. One good product for ticks is the Seresto collar or the Virbac Preventick collar. These offer protection from ticks (Seresto also helps with fleas) for several months.
