I like cats but dogs are so loyal and loving. One of mine is quite independent - and whilst she's pleased to see you and likes to come for a fussing, she won't stay. She likes going off and playing with her toys and doing her own thing.
My other dog is like velcro though. I know he loves me; he shadows me everywhere and always likes to be close to me. If I go away he pines and doesn't eat properly. He is old though and I am dreading the day he is no longer here
