I've already tried cats Well, I started feeling guilty. A dog is not looking promising Please tell me about dogs. I can't afford a horse. What are some other options for outdoor pets? Something that can be penned up and still be happy would be preferable. I can afford to build a small pole barn, but not anything big enough for a horse, donkey, etc. I've thought of goats, but don't know much about them. I've also had someone suggest rabbits, but don't know much about them either. The kids are 6 1/2 years old (twins, boy and girl).

PS: Some of the things I'm interested in learning about regarding various pets are: initial cost, cost of spaying/neutering, cost of feeding, cost of shots, and any other hidden costs. Any help regarding where to get them is also appreciated. Also, what arrangements need to be done for their care while we're gone on vacation.
