Hi, I'm looking to buy a dog but I would like advise on what breed(s) would be best for me. I've owned 4 dogs in the past, however I'm not experienced with training because I was a kid and my family took care of them. I'm looking for a dog that isn't too hard to take care of (ex. how huskies are escape artists, or dogs that tend to be aggressive) that is a medium size, or large in necessary. Next summer I'll be moving on my own and would like the dog to be a companion to keep me company and allow me to feel safe when I'm on my own. I've already found a trainer who will help me with obedience training and done research on many breeds, from beagles to labs to rottweilers but I wanted advice from some experienced dog owners on what breed(s) would be best for me. Also, I already have a cat so I'd prefer a breed that's easy to socialize or advice on how to socialize the two. Thank you in advance and I really appreciate your answers.
