How many pets equals too many?

We have had our English bulldog, Gunny, for a few years now. He gets lonely. We tried getting a female companion for him. While he was extremely...ahem... excited about her arrival, she didn't stay with us for long. We live in the country. We don't have a fence. She was deaf. I kept having to go out into the road to get her. I was afraid that she was going to get squished. She went to live with a very nice family who had three other dogs and a large fenced-in yard.

My husband knew that I was very worried about Gunny being lonely. (Isn't that sweet?) He got me a really cute and sweet doxie for my birthday this year. His name is Charlie. Clay, our youngest boy, claimed him. Charlie and Gunny do not really get along well.

Our oldest boy, Taylor, brought home a puppy a little over a week ago. His name is Behemoth. Seriously, that's the name the little guy got stuck with. He will be a monster of a dog, though. He's half black lab and half Saint Bernard. He is a pooping and peeing machine. Too bad he isn't house trained...

All of the dogs are loved by someone in the house. Damon doesn't really care for any of them. He says that they are always underfoot, and they are. He says that they are stinky, and they can be. He says that they shed like crazy, and they sometimes do.

So... how many dogs are too many?
