I have a 5 year old dog and a 2 year old dog comparable in breed and size. We'll call the older one Barky and the younger one Crazy. I love Barky much more than Crazy, even though Crazy is much sweeter. I've had them both since they were puppies, but it seems the bond is much stronger between me and Barky. In fact, sometimes I like to be mean to Crazy just because I don't love him as much as Barky. Is it normal to love one of your pets more than the other(s)?
