I was walking my son's dog on July 6, 2004 A rotweiller came charging from about 100 feet. The dogs owner was calling the dog back, but it attacked my son's dog anyway. I did a lot of dancing to keep the two dogs apart, and received two teeth punctures on my left hand in the process. After the owner was finally able to restrain her dog, I continued home. After examining my son's dog, we found that she needed stitches. To make a long story short, we sent an itemized bill to the owner of the other dog totalling about $265.00 which was for the vet bill, my doctors visit for a tetnis shot, and lost wages for my wife that was $96.00 for the day she had to stay home. The other people sent us a check for everything except for the lost wages, but also wrote on the back of the check something that said "Endorsement of this check releases Rob and Kerri from all liability due to the incident on 7/6/04 with my dog Abby" I am not really upset about the $96.00, but my son is looking into the possibilty of bringing charges against those people, and maybe even having the dog put to sleep. This is not the first time this happened. We were attacked last year also, but there were no injuries involved. My question is about that statement on the back of the check, is it valid ? If I sign and cash the check will my son loose his right to bring charges ? Many thanks from Penna.
