Place to place, there are very different laws, rules, customs & compliance regarding dogs. And there's often more to the story than meets the eye as well.
This county has a Leash Law. Outside of fenced personal property there are few legal options for letting any dog Off Leash. This is a free County Dog Park, there's a membership Dog Park & one provided by electrician's union nearby-all designated Off Leash. There are at least a couple of signs posting rules & a LOT more Fine Print in the law. Free running dogs that run amuck were automatically at fault, an escaped dog is a liability.
In Kal's case the couple carried extremely attractive treats in Dog Park. Bits of hot dog crisped in microwave & had given treats to Kal. The attack happened when she was giving treats to Duncan & Kal was looking for more. We'd been trying to help socialize their other dog. Find it ominous that they haven't been seen again at Dog Park. Still don't know if Duncan was hurt?
Took the SS staples out myself by using alcohol swab, small diagonal wire cutter to snip staples in middle & forceps to curl the ends out. Only complication was Kal finally managed to rip at 1 of the staples kick scratching his ear w/hind foot! So more antibiotic oinment & waited 12 days, instead of 10.
Didn't see how well aligned when staples went in, but as healed, Kal has a notch. It'll be his Frankenstein ear for awhile. That's 1 big beautiful velvet ear that's scarred for life.
