Hello, So a close relative of mine just got a Dal but turns out due to their mental health can't take care of it so I'm taking over and would love to make him my own. However, this pup was brought to me at 5 months old and I have a 10 year old German Shepherd. Puppy seems to do ok but not completely fine with him. I socialized my dog from the moment I was allowed. But this puppy has only been socialized with its parents and litter mates. Is it too late to socialize him successfully? When first meeting my dog he barked wildly at him. Now he'll growl a bit before barking a few times. I would like to have him be able to meet other dogs without going crazy. If I can't socialize him successfully, I'm going to have no choice but to return him which I would like to avoid. I'm not familiar with Dals and I know they're on the thin side but he seems too skinny (21 lbs), like I can see his rib cage pretty well and hip bones and don't want him going back to that "breeder". Also, he's 5 months and the breeder has only taken him for 1 round of vaccinations! so I don't even think I can start socializing him right away to make things worse.
