This is a funny little video of Jax attacking a tennis ball. He is a miniature Jack Russel and it shows . He has the attitude and he is always making me laugh and he is always up to something especially when he is in one of his moods. Found this ball and gave it to him and he would not give it back lol it was so funny watching his aggression towards this ball maybe because he smelled another dog on it I am not sure but it made for some quality pass time with him. Love this little fellow.
