My 14 year old Jack Russell Terrier is sick
I have a 14 year old Female Jack Russell (Which weighs 22 lbs.)and she will not eat. She drinks lots of water, and lately I've been noticing she's missing patches of fur, she's heavily breathing, and she has no energy. She also has cataracts in her eyes, and every time she is heard breathing, it sounds like there is liquid in her lungs. She also has a growth on her leg, which looks almost like a cancerous buldge. What does she have? and what would you recommend for her?
