I have had three dogs, all of which I were/am close to.
Vader was a black lab, got him when I was 5, died when I was ten, long story about how he died but the quick version is that he ran away and somebody shot him.
The second dog was Sarge, a yellow lab, got him a few months after Vader died, he was only 4 when he died, he got blasto mycosis which is a fungal disease that hunting dogs inhale when sniffing the ground. Long story short, he did not make it.
The dog I have now, Ozzie, a "red" lab (looks yellow to me), is one year old and dumb as a brick but i love him to death. You know how dogs pick their favorites? Well I'm finally the dog's favorite. i can tell my dad is kind of bummed about that, because he was the favorite with the other two, he said he wants to get another dog next winter to keep Ozzie busy, but I know he just wants to be the favorite, so I'll keep my distance with that dog.
I have had close bonds with those dogs, my dad always tells me never to get to close to a dog because they don't last long enough and it's not worth it, but I have to disagree, i say get as close as you can while they are there.
I've had fish and have three geckos and a bunch of cockroaches, but it's kind of hard to have a bond with those.
