Is there any child-friendly dog that could be happy kept in a small flat?
Okay, the circumstances are bad. But, there is a way. The English Cocker Spaniel is good with kids but you will have to get another dog/cat to keep it company. If you don’t get another dog/cat to keep it company, the dog can turn aggressive, destructive and sick. Make Sure Your apartment is well ventilated and there is a lot of sunshine coming in. Don’t keep your dog in a dark flat. Take him for a long walk before you go out on those three days and after you come back. On those three days, I don’t know what you are going to do about the toilet part of the problem. Another thing, please keep a lot of toys for your dog and if possible have someone drop in at lunch time to take him out for some fresh air. Most importantly, if the circumstances are still bad, please don’t get a dog. Wait a little till circumstances are better. Also, leave the dog free in the house, don’t tie it up. That can cause severe mental disorders.
