Jessica, I feel your pain!!
Shai is the master Houdini!! For awhile there she escaped quite frequently. I don't want to say this but she hasn't for awhile, now I probably will jinx myself, tho right now she doesn't feel very good. Some people don't think their dogs are a threat. I have only had 1=2 dogs that are purposely off leash come up to us when walking. Another dalmation pulled his chain out of his doghouse and came flying up to us but when we ignored him he stayed where he was. Our dog we had when I was little was hit by a car b/c she went running after a dog that was running beside its owners tractor and going down the road. Tho I really can't say much I grew up with our dogs never tied up and always outside and never on leash. That's just the way it was!!
