The most I've ever had was two. I only have Cledus now(pic below), my mutt dog, lol. The adoption clinic said Boxer mix, but I don't see any Boxer in him at all. So, at first we saw St. Bernard due to his coloring, but he is WAY to small to be a Bernard. (darn it!)
My previous dog was a Collie, Sara. She was 11 when she left us. She was the best doggie ever!
I want a Newfoundland!!!
And I have also had several orphaned mutts, that either I found or Dad saved. Which they never said long. Just long enough to get better then they were off again.
