Hello. I'm thinking and taking my time to find another dog to join us. It's just me and my husband Nick at home with our 5 year old shih tzu Louie. I have allergys so need a dog that doesn't "shed" as such, as I know all dogs lose there fur/hair but in my case ones that you have to comb the hair to get it out. Hence why we have a shih tzu, well that is one reason . The other was a small dog was only accepted where we lived. Louie also, has his requirements, he doesn't like dogs much bigger than himself, as he becomes defensive if, they are young and boisterous. I'm not sure what he would be like with an older dog though as he seems OK when out on walks... We are home a lot of the time, like walks, we have a quite house as, there is just the two of us & louie makes 3.Any idea on breeds will be appreciated.
