[Bobby dog]

You’re welcome. I have some kind of a heeler mix. He’s a ton of fun!

Hopefully some other bully owners will stop by with some input.

I have to compliment you on taking the time to think about choosing what dog fits your life style and caring for your adoptive pet prior to bringing them home!

I think it’s important to consider your dog’s life stage and activity level when deciding on what to feed your dog too. In regards to protein I think digestibility is important to know.

Here are a couple of articles on the subject:
