I'm a cat person but I've owned dogs as a kid and I seem to have a bond with animals. I've put on a few pounds this past year and this should help me get back to a weight that's comfortable. So energetic dogs shouldn't be a problem my dog dusty was a small breed what you would call a mutt . Not sure what the mix was Maybe a Terrier poodle mix , but we got it at the Brighton mall .she lived a long life chasing tennis balls until she went blind and then we put a bell inside and then she could find it anywhere. Right now I have two cats one male one female kilo and Ella they are the goofest cats I've owned yet.
