Hello all,
I'm writing today to get advice and possible help. I have a 2 year old silky terrier with bilateral patella luxation. they were at stage 2 and my vet said not to worry, but this past weekend she stopped walking due to her knees going into stage 4. my last dog, (who was killed about 2 months ago in a horrific car accident) had 3 knee surgeries, putting me into credit card debt for the same patella luxation problem. I cant afford to go through the same financial draining again. I'm still paying off my dead dogs bills. what do I do? she's not walking and it kills me to watch her. she normally flies! I'm trying to do some research regarding pro bono doctors but I don't qualify. (apparently the little I make over qualifies me) any advice would be appreciative.
