I'm no medical expert, i was just came accross this site and was wondering if anyone could help.
My dog, a collie, is about 10 years old, (we got her from batasy dogs home in 2000, she came from abusive owners.)
She's always been very lively, the kind of dog that would want to fight other dogs, even though they are 10x her size and we have two other labrodors, which are bigger than her, but she still has all the authority in the house, haha.
Anyway, recently i've noticed about 5 big lumps around her neck, and she seems to be very tired and weak.
Normally she would play games with the cat and case him around the house, and wouldn't let the cat even come near the living room, but recently she doesn't seem to have the energy.
Does my dog have cancer? or maybe is she just old?
Thanks sooooooooooooooooooooooooooo much, if you can help or give any advice.
