Another pet, good or bad? I have a dog right now.?

That's happened with me too. I have 3 dogs but they all seem to not notice me when my dad is around lol. Basically, that happens because dogs are descended from wolves so they think like a pact. Usually the big strong male is considered the leader of the pact. Hence, your dad. It's not that your dog loves your dad more. It's because he's like your dog's leader. I've had dogs all of my life. It has to be over 10 dogs that I've had and it's always the same thing. Eventually I grew to understand why they do that so it doesn't bother me anymore. There is a chance that your next dog will do the same thing. I think that you can handle another pet. However, make sure that the dogs are introduced to each other for a few days before being put together depending on your other dogs temperament. There are cats that have very thin short hair. I personally have never owned a cat but I've noticed that they don't shed as much as really hairy cats. I also have a boxer who has very thin short hair so they don't leave hair all over the place.
