...of it this morning. Help? Is this an early sign of something... ? I'm really worried about my dog. She's an 8 year old labrador retriever. Yesterday she wouldn't eat anything. She started eating again today. (thank goodness!) Using the bathroom fine ... but acting not like her normal self. I am definately going to take her to the vet if she still appears to be acting strange in the next couple of days. But, I heard of dogs not eating when their liver is failing. Am I over-reacting? What are some symptoms of liver failer in dogs? Could it be cancer? Or is she just getting older and changing? I'm so worried! Any help would be greatly appreciated!
