Oh no! I feel badly for Ollie and you/bf! Thankfully you were able to get immediate attention. What great folks driving you to a vet
I for one, will never take my Yorkie to a dog park; for the exact reason that I would not be able to trust another dog. If I had a bigger dog (more than 15 lbs) it may be another story. One bite on my 8lber could be deadly. I sure am glad that your Ollie survived and is showing signs of being back to himself. Agreed to phone Animal Control. Not sure about court though, as it may take more energy/money w/out the results you should get. Getting legal advice may be good idea before going forward, should you wish to go that way. Is $400 worth your precious energy on someone that may not pay in the end, or is it better spent with Ollie and your loving family? Being a part of a trial/court recently, I found it to take SO much energy and created a lot of stress. I would hope that Animal Control would look after the owner and his dog; especially if this dog has bitten before, which I suspect has happened. Makes me angry that some dog owners, no matter what the breed of dog it is, do not take other dog's safety into consideration. Nasty people!!
