The pup is almost 4 months old took to the woods and the dog was whimpering non stop and would not walk in front when the dogs home it climbes up on anything it can to get away from a 6 pound shitzu???

I just bought my first plott and he is shaking scared of my wifes shitzu and runs around with his tail between I am a little concerned since these dogs have a reputation of being so gritty.
