My mother in law is considering getting a dog, however, we don’t know what breed to get. She is 73, lives in an apartment, is willing to walk the dog for around 40 mins. Preferably a quiet (and lazy,) relatively small dog - and loving, ( the main reason she is getting a dog is for companionship, she is now a widower.) We have looked at cavaliers, but have heard they are prone to heart and skull issues? Other dogs we have looked at are; cockapoos, cavapoos and English cocker spaniel (show type.) Cockapoos and cavapoos can be even more prone to health issues and their temperament can be unpredictable, apparently. We particularly like the English cocker, however we have heard mixed comments, some saying that they need lots of excercise, and others saying that they only need 30 mins? If there is a breed we have missed or if one of these breeds are suitable, any advice would be appreciated!!
