I can feel your pain when the furpups run for greener pastures. Being a mom to a greyhound we had it often!
Shaianne would "break loose" and once she ran down to my dad's work, dad thought My mom had her until he saw she was alone. Then she got loose twice down in my sister's subdivision and headed for 2 major highways. She got loose and ran over to the nursing home across the street. The best one was when she was at my parents overnight and got loose 2-3 times in one day and then he had her down to my grandparents and popped the collar over her head and took off in a snowstorm and was racing the snowplow. My dad thought she was a goner until she passed the snowplow. And turned around and headed back towards him. Then her collar broke down at my grandparents and her flexi leash came flying back to my head until I ducked. Then we chased her in the snow. It was a trip!
And Keegan has had some close calls too Thank God people are careful and compassionate and at least slow down for her when she runs across the road. At least they don't try to run her down, yet anyway, I am sure one day an a--hole will drive by and not care.. Let's hope not tho. She can run fast but not near as fast as Shaianne did!
