Beagle is not a bad idea. Maybe look into a Bulldog as well. Stay away from maltese, yorkies. Dachshunds are pretty good too if you like weiner dogs.

The issue with bulldogs is that they require some grooming attention. They are one of my favourite dogs, them and Staffordshire bull terriers (can't own those in Ontario though). Bulldogs require help with cleaning under their wrinkles because moisture can build up in there and cause skin sores. It's more common when they are younger because the folders are bigger and all over their body. But still a great dog, all the weight of a big dog in half the size

I also gotta say that I absolutely love my Springer Spaniel. His name is Ernie, he's a great dog, listens great, is great with kids, and new people. He's also very protective, he will sleep outside my door all night long, he wont move unless he hears someone at the front door. Besides that, he will lay there. He has always cried when he needed to pee, and was very easy to potty train. The main issue with them, is that they stay puppies forever. They will start to look older, but never stop wanting to play like a pup, so they can have a little more energy than you may like. They aren't as bad as a boxer, or a border collie, but they are definitely playful.
