I've cried with laughter at some of the stories above. I have a 8 year old lab springer cross and 1 year old cockapoo (as well as two older cats). I kept most after I separated from my ex and acquired the cockapoo from an elderly person who struggled with him.
Anyone who is havering over getting a dog, or isn't keen on the poop, sick, stinky, shedding, embarrassing expect of dogs, please don't get a lab springer cross. She put me through the ringer as a pup (and still as an older dog) with the upset stomachs, vomming, rolling, accidents which end it large vets bills, shedding enormous amounts of hair, stealing any food and generally being a nightmare. It's endless and as a 8 year old, you'd think she grown out of it, but nope. Apparently not. She's still a very high energy dog, prone to running through everything and eating anything or everything, yet gets the shits if you change her actual dog food. I had no idea just how hard she had been until I got the cockapoo who has been nothing short of saintly in comparison. Quick to learn, no stomach upsets, never eaten socks or beading from a blind, he's a country mile away from my lab springer cross at the same age.
My honest opinion is do your research if you want to get a dog. They are beautiful wonderful creatures, but breeds vary in how much exercise they need and some of their better or worse personality traits.
