Are these breeds really that hard to keep as pets? I have been doing some research on them and a lot of trainers say that if they aren’t going to be working dogs or competition dogs, don’t get one. Is this good advice?

I’ve trained a few retrievers. And trained a bunch of dogs in obedience. Some were mine and some weren’t. But I’ve been thinking about getting one and doing some obedience competitions. But the dog would probably be more of a pet than anything. What are y’all’s thoughts?
