We currently have:
Keelta, a Shetland Sheepdog (one of those mini lassie dogs). We got her around when Emma was born for Morgan, but she ended up bonding more with Emma, so we usually refer to Keelta as Emma's dog.
Shaman, another Shetland Sheepdog. Morgan got him again as a gift a couple years ago, and they are absolutely inseparable. They have such similar personalities too! They're both so neurotic. Shaman has certain things (ringing telephones, putting away cutlery, sneezing, vacuums, running microwaves...) that send him into these fits of anxiety where he paces and barks and scratches the floor or himself until whatever it is has definitely stopped. He does other things too, and it's so funny to watch.
We used to have: a hamster named Scruffbucket, a cockatiel named Baby, various fish, a cat named Beauty and another one named Thor, and our most recent loss was Morgan's long-haired chihuahua Bennet. The dog wasn't legally his, and he had to give it up to the owner last year.
I'm actually more of a cat person than a dog person, but my husband is allergic and Morgan is a very big dog-lover, so we have dogs.
