maybe it could be allergies or he is allergic to some thing my dog had this before we put antibotic on it and it went away
thanks for your advice i am going to take him on friday . iv made a appiontment once again thanks audrey
Your best bet would be to have your vet take a look at him. If that rash is due to dog bites, he'll probably need antibiotics. That looks like a right nasty rash, and could be something else - like mange or flea bite dermatitis, all of which need a vet's attention. Enjoy your new pup!
