Whereas one of my reasons for choosing a rescue was that if you get one from a charity that does proper homechecks (eg asks lifestyle questions not just have you got a garden) and fostering you get a dog "that does what it says on the tin". I knew EXACTLY what I was taking on.
There's a massive difference between a pound dog (eg Battersea, council pounds) and reputable rescues that I don't think there's enough awareness about amongst parents.
Beagles are proper pack animals. That means that they are very unsuitable to be left alone for more than a couple of hours on a regular basis. The breed is prone to seperation anxiety which can result in awful behavioral problems. They have a reasonable lifespan so if you think you may eventually want to go back to work even part-time a beagle may not be for you. (Not all SAHM's spend all day, every day at home tied to the house by the time they've been to Mum & tots groups, met up with friends, done a course, gone shopping etc).
They need a decent solid hours run once or twice a day in ALL weathers, & have a tendency to be a bit naughty/greedy with food. I felt that it wasn't really a good breed for city life.
On the other hand, compared to many breeds they are relatively free of health problems, & sweet tempered (which is why Americans and laboratories like them so much).
I'm too bone idle to own a beagle. We chose a whippet cos I don't wanna do 5 mile hikes in the snow, or be permanently tied to the house, (DS's hosp appts can take 1/2 a day).
