Aw poor Titus. So you said his mange is all good what skin infection does he have? My vet informed me that its a little easier for a puppy to recover from mange then an adult dog. How long until your started being his normal self? I hate that BANE isn't acting like his normal self but my vet told me to make him go on walks. It's just so sad to think of the things that our dogs can get but by lookin at his pics he is lookin good especially if you said it was worst then my dogs mange. But as for the breeder I did not get it from Craigslist It was from a website and we went to his house and he had 4 litters but I picjed the runt of the family. As for Titus I really hope he feels better! I kno how you feel
A breeder having four litters at one time and letting a buyer just walk in and pick a pup doesn't have the sound of a good breeder. I doubt you'll be able to make any headway on notifying the breeder or getting any assistance from him.
Make sure to be washing bedding and his collar or harness regularly since you said he has sarcoptic mange also.
I've cared for two demodetic mange puppies. Neither was as bad off as your puppy when I had them; one because we started treatment earlier as soon as we pulled her from the city shelter and the other who actually started off as bad as your puppy (no fur at all) but had made great progress being treated in a shelter before she came to me and then very good progress during her month staying with me. I've seen a few really bad cases that were successfully cured in about 6 months, of course getting better little by little the whole time. As the puppy ages, their immune system gets stronger anyway so that helps.
Your puppy probably feels miserable with painful, itchy skin so he isn't interested in playing and walking. As his skin heals, he should get back to his normal self.
Demodex mites are carried by all dogs, they do get them from mama, but a healthy dog with a healthy immune system can keep the mites under control. Low immune system, stressful situation, and low quality food or lack of food all contribute to making the dog unable to keep the mites at bay.
So it helps to counter-act that: feed as good of quality food as you can afford, many dogs do well on grain-free; add some fish oil or feed sardines (packed in water, no salt, regular grocery store kind). Try to make his environment as low stress as possible- things like not introducing him to lots of people or busy situations or taking him places that he finds stressful.
I used a benzoyl peroxide shampoo,
something like this one and gave a bath every 3-4 days. It helps prevent infection, cleans the skin and helps remove the icky smell yucky-ness mange crud. My vet also put the puppy with the really inflamed skin on an oral antibiotic (she had basically zits all over her belly, neck and legs). I dosed with oral ivomec daily, I suppose the shots would work the same. My vet said dips are kind of old school and the meds+shampoo was sufficient so they didn't get dipped.
