I love your puppy... I have a jack russell too (obviously from the picture). I previously had a rat terrier and she was a great puppy. Enjoy your new puppy. They will definitely keep each other entertained and run around like crazy!
Yes she is and very busy at 4 years old. We are crazy enough that we are getting another puppy - a Rat Terrier (like the Jack but with stand-up ears). Not born yet - and we have a 13-year old cattle dog that will think really are nuts. But she is pretty patient. The Jack is named "Bo" and we are interested to see if she mothers the new puppy
