Everything that everyone has already said it so true! When we first got Toto we were advised not to use anything that was not recommended/approved by our vet! I don't even change her food without consulting Dr. Lucy. There are "same name" products that can be purchased from pet stores, etc., however, we only buy what we use from a vet. She always tells us wherever we are ... go to a vet to buy any of this or call me and I will send it to you! The "over the counter", same name stuff is not always the same as the "vet formula". The first time we discovered fleas on Toto, I called Dr. Lucy to ask her to recommend a good flea shampoo ...
she didn't recommend ANY flea shampoo! She told us to go to a local vet and get a vial of flea treatment & a syringe ... bathe her in her regular shampoo, kill all the fleas, dry her and put 1/2 the treatment between her shoulders. We did ... it worked ... been using it ever since! She did finally "graduate" to a full dose!
