Bringing a new puppy in
I have a male Jack Russell who is about 9 years old and we are planning on getting a miniature Jack Russell pup. However I'm worried about how my JR will react to the new pup as I would be worried that he would be too aggressive and bite or hurt the pup. He doesn't often get the chance to meet new dogs and would be quick to have a barking fit if he sees one on the street or TV. He gets on well with my grandparents dog as he as known her since we got him. I was hoping to get some advice on the best way to introduce my JR to the new pup without the risk of him hurting it. Thanks :-)
