So, I was looking into getting a couple tennis balls for Ryder, and I found out that they are actually dangerous for dogs? How did I not know this? I am wondering if I should still give him one, maybe a Kong brand, it'd cost more but would it be a better choice? Or do you have a better suggestion on what kind of ball to get him? He will be 8 weeks old when we bring him home, and I want to keep him acquainted with chew toys in the beginning and yet still (maybe I don't have to teach) play a game fetch, at least learn how to. Any help would be appreciated. As of right now, he has a Fetch & Glow ball and a pack of 3 tennis balls, but I'm starting to think I don't want to give him these. I know I sound paranoid but he is going to be my FIRST fur kid.
