Please help !!!!!!!!!!

My dog has changed in the last 6 months, she is loosing weight and we started taking her for a walk and she tired after a few blocks. It seems it is harder for her to jump on our bed to and her bark use to be loud and now it is soft. She is a black lab with golden retreiver mix and she just turned 11. we have had her since she was 7 weeks old. what is appening to her, she has gotten alot skinner too. please help as she is like one of our children..thanks Karen

This is a senior dog and many things could cause what you describe.

What does your vet say? What tests have been done to find out what it is?

I would call your vet..

I agree. You need to see a vet.
