We are so upset. We purchased a 12 week old puppy from what we thought was a reputable breeder. Her mother bred for over 24 years and now she is breeding. She has a few females and two males show are all in her home. She was adamant about not letting us have pup untl 12 weeks because of her tiny size. She fed high quality dog food, Orijen. We knew this pup had two tiny spots of mange . She said not to worry. I already knew they get it from mom and lowered immunity. She gave us shampoo and Goodwinol ointment and said it will go away as her immunity builds and not to get next round of shots before it goes away. We took her for exam and vet said she needed Ivermectin. Also faxed all the info that the breeder said she wanted from vet visit. Vet said she was a bad breeder and should not have released dog. I felt that the sooner I got the pup the better it will fair. I felt it was more stressed there with all the dogs and not getting full attention. So now five days later it seems she is scratching more and more little hairless spots. Plus where vet scrabed it's scabby. Vet said to throw away the oil and shampoo. I understand that they have insecticide in it and will only further irritate her skin so I am not using it. Does anyone have any experiece with this. I am so afraid of the Ivermectin being so strong of a med but I am giving it to her. I don't see an improvement though. we love this little one and would never give her back. We had a rescue before this with many help problems that we were constantly nursing and we hate experiencing this again and seeing this 1.8 ounce pup suffer. Please give me some reassuring news about this type of mange.
