I cant be bothered with dogs at all. I think they are pains in the arse to be honest. They dont deserve to have stupid folk lifting and laying them as if they are a lifestyle accessory accessory though.
Both our cats were rescue cats and one is just a big daft lump that would be happy anywhere but the other one was a b*****d when we got her and she took a long long time to settle down. She is a nice wee cat now that she has got her confidence back and feels safe but she had to be worked with.
Anyone taking on a pet should have a fucking think first. They can be expensive, demanding, time consuming and all the rest of it. They are not toys.
