 That dog is going to wreak havoc in your house. Delja Mallon wants to say if you like to get out and you like to hike and you're active, get a dog that's active. You know, get a chihuahua if you don't or a smaller dog or an older dog. Older dogs in the shelter desperately need to be adopted and in rescues. They're one of the hardest dogs. Be aware, though, that when you adopt an older dog, you're adopting probably some health issues.
