My son has a new puppy (shepsky) that is just 6 weeks old as of Friday August 28. They both live with me. My son went and picked up this little guy on 8/29. The puppy (Argos) was understandably nervous and was a bit shaky on the ride to our home but he did very well . We noticed some dry flaky skin that looked like cradle cap on an infant. Figured it was because he was so young and we had never had a puppy that young before. Well some of the dandruff started to move and we realized he has lice. We have been bathing him and brushing him daily and those are starting to die off. I am worried because he is still isn't eating and the breeder gave my son adult food for him ( we bought puppy food). He drinks water like crazy and he pees and poos but he just isn't active like I think he should be and tonight his breathing was faster than it has been. He should also be eating right? My son has a vet appointment on 9/3 in the afternoon. They did not seem to be concerned but I have all of these bad thoughts running through my head that something isn't right. Does anyone know if I am worrying for nothing or what we should be doing?
