Just had to put down our jack russell back in October and she was one hell of a dog. I have had a bunch of labs in my life, but our jack was the smartest dog I have ever seen.

She lived to be 15 and was pretty hyper for the first 8 years or so but calmed down a bit. We still have an english lab that is loyal as hell and I love him to death, but that jack was probably the most favorite dog I have ever had.
