I am considering getting a dog. My son is 9 and absolutely loves dogs, and I would really love to have one, and not just because they are cute. However my son has several allergies and he might be allergic to dogs as well, although we don't know for sure and he seems fine with other dogs. So what I would really like is to try having one for a few weeks before I commit - I know this sounds awful and I don't doubt it would be loved and well cared for, but I don't want to cause discomfort to my son or return the dog - it would break our hearts not to mention the poor dog.
Also, due to the size of our house, we can't have a big dog, think Cockapoo size. I would really like one from a rescue, not a breeder, and for many reasons I don't have the energy to commit to having a puppy, but an older dog. However, I didn't have dogs growing up and I know nothing about what having one actually means in practical terms. Also, unfortunately we don't have anyone to care for the dog when we are on holiday abroad, so we would have to use a kennel or dog sitter. And if we go away for a long day and can't take the dog (this would be about 3 times a year) would this be cruel to the dog? I don't want to neglect or distress it. Any useful words of advice or experiences worth sharing?
