So, I'm going off to college next year and my mom is at work for the majority of the day. Because of this, we got our dog (she's 3 years old) a new friend to keep her company.
We brought home this new puppy (she's almost 3 months old) and my older dog seems to be a little bit frightened by her which is understandable since my older dog has hardly been around other dogs so she's also more of a human lover than a dog lover. Our puppy is used being around more dogs compared to humans so she's always trying to play with my older dog. I, myself, haven't been around many dogs and never more than one at once for a long period of time.
When they play, they seem to play rough but I looked everything up and they don't seem to be fighting, just playing. Because my puppy is a Jack Russell terrier mix, it does a lot of biting. I've read that breed has a tendency to bite which explains why she does so often. Because she doesn't have the majority of her teeth in yet, I'm not so concerned about her biting hurting my dog, but I'm concerned if it's malicious biting or not.
My older dog doesn't bite as often, and when she does you can hardly even feel it. But my younger puppy bites my dog's neck, ears and sometimes tail. My dog doesn't seem too distressed about this, but I don't want it to continue in the future in case it is malicious biting because she may actually injure my dog when she has a full set of teeth.
