Poor Drake, so glad he is on the mends. Just this past weekend I had to take Miss Lucy (Ricky's cat) to the Vets because of a cat fight. I didn't see any real signs of a fight at first but one of her eyes looked sore so I thought better safe than sorry. She had a scratch on the inside of her lower lid. Now she is on antibiotics. Not a big deal but all part of ownership with animals. I agree with everyone else about unleashed dogs. I can never let Ricky off the leash or out of my sight because of so many unleashed dogs running around.
The important thing is Drake got the needed care. I hope you are able to convince your neighbor to pay up but be careful. You may be in for a long time with an angry neighbor. It can and often does get ugly.
