have you had dogs before?
If you were the one saying something about getting a house dog, then you're in for it.
Don't think they're good house dogs because they're small. I have a 100 pound Akita thats a great house dog. He's just like a rug you need to feed from time to time.
jrt's are smart dogs. smart dogs get bored. bored dogs mess shit up. you get a bulldog, and you leave for work, he just realizes you left when you walk back in 9 hours later.
If she doesn't get a LOT of exercise and attention she will mess your house and your yard up. I have a border collie that gets an hour of HARD exercise per day, and he recovers in 5 minutes and starts bringing me a ball after we get home. he lies on the floor staring at me when I watch TV, and bolts to the door EVERY time I stand up.
don't be like that other guy that got rid of his dog after 5 years. That's not good for the dog or you, so don't get it unless you're ready to really put the work in for the life of the dog. I've had lots of dogs and love them, but if you can't give a dog proper attention, you're best not to get one at all.
dogs are much needier than cats. they're pack animals and form very strong bonds to their humans. they don't like being left alone. they're much happier and healthier with regular exercise and attention. Ours get walked twice a day every day. And by walked, I mean RUN. chasing balls, sticks, swimming, playing with other dogs. that obsessive behavior of JRT's is cute, but its what makes them terrors and its not something you can get out of them with any kind of training.
if a dog is obsessive like that and doesn't get what she needs, sometimes they'll just bite and scratch themselves till they have raw spots.
that's all from me.
