Go Get the Dog. Right Now. Getting it food is great but all animal control will do is give the people a warning.

Get the dog so it can get to the shelter. Fix the chain. Give it some blankets. Pail of water and food.

Thats the two choices you have.

Grow some balls and take the dog and then find it a home.

Laying in the snow with no shelter. Come on already. How long have you been watching this happen already. This isn't somthing that just happened. What about this summer and fall. What was going on then...? No attention paided to it..?

Offer the bitch some cigarettes for the dog.
