Currently, my dog lives outside. It is winter here but it does not snow. She has her own dog house and is tied during the night. I read from people saying that it's cruel keeping a dog outside,tied to it's house. However, I am afraid that if she isn't tied,she will run away. She did that a few times because occasionally, some one goes in or out of the backyard through the gate fence. She use to live indoors when she was a puppy but my uncle (the owner of the house wanted her outside). I couldn't really train her. She is so hyper because she is half chihuahua and half smooth collie. She speeds run a lot and jumps and bites me.

Build a fence.
Google positive reinforcement training
She is hyper because she is chained constantly.
She needs training, exercise and attention. pets question and answers,www.5d2d.com
If you cannot give her a better life than being isolated chained to a dog house find her a home that will.

Re-home the poor dog. No dog should have to endure a lifetime of loneliness.

Dogs are man's/woman's best friend. This means your constant loving attention is needed by your pet. They cannot provide for themselves as they look to you as the alfa dog, their master. Your dog is hyper because it craves attention and as it comes from a breed of toy dogs (chihuahua) it has a tendency to be over playful. Give it the love and care it deserve. It is cruel to leave your dog outside in winter. If your uncle does not want him inside, find someway to keep him warm and comfortable in her house. Do not restrain her as it makes matters worst and the dog will be vicious due to exertion. There are a lot of dog houses designed with a grill door for them to stay in. If you cannot find one, let some workshop fabricate it for you. Hope this helps as your dog will serve you better if you show your love and attention.

Sounds like she just needs some attention. There is NOTHING wrong with you keeping your dog outside as long as you spend time with her and give her some exercise daily, be it a walk or just playing ball in the back yard. Show her some affection too. I'm not saying you don't, I'm just telling you because it's what dogs live for, our love and friendship. Sounds to me like the nipping is her trying 2get ur attention 2play.

There is nothing wrong with tying a dog up to keep her safe. But its all on YOU if you don'ttake care of her. She is YOUR responsibility, that means you have to take care of all her needs, not just the easy ones like feeding. You need to take care of her social need to be with you, and she needs to be trained, and she needs about an hours worth of a walk with you as the role of leader. Maybe if you train her your uncle will be more abpt to let her in. Shes not hyper because of her breeding shes hyper because she has a lot of excess energy that you need to find an outlet for.

If you cant take care of her properly then I suggest you give her to someone who can.
If not you will just be another unresponsible pet owner
Also tying up a dog should be your last concideration, fennces are always better.

find her a better home where she will get more attention. That's why she jumps & bites & runs around all crazy
