This is regards to the pit bull puppy i had posed earlier. He does not have the fleas any longer.?

He has had his flea treatments. His cage door is left open for him togetout. he chooses to go back in after they bring him in from outside. They are good to him. He is just like a child to them. They have already spent thousands on him. this is not a one time visit to the vet this is numerous sometimes 2&3 times a week. He has already been tested for Lyme disease. I appreciate every ones help. they live in Fayetteville, N.C. I had told them since they have a new baby it is very hard on them, but they care for him. If anyone would like to care for the puppy, just let me know. i know they would appreciate it or if someone knows what is wrong with him. They will be coming to Crosby,Tex. for our Christmas. Maybe someone knows of a vet here to help. Thanks to all
