Thanks, guys He is cute- but he is definitely a LOT of work. I have no clue what he is mixed with- he's about a year old and weighs 35lbs.
That was actually the first time I let him and T-Bone play like that- they have only met each other the last two days with Bo being leashed and it build up to this constant play-bowing and tail wagging, so I figured we'll give it a try. They play together fabulously.
