Why does my dog have a growing lump on her neck?
My dog was attacked by something a week ago, but we don't know what attacked her and left bite marks on her snout, under her neck and by her shoulder. Although her bites didn't bleed. Since the attack a lump on her neck has grown bigger. This bump is on the left side of her neck. She is a mix breed of Chihuahua and an outside dog. We have her inside now and she's eating normal now, but we are very worried about this lump. Please help me.. what can it be? I can't afford a vet visit...
