In today's "Throw away society" I guess this is to be expected.
I rescued my boy Astro from a kill shelter three years ago. He’s a pit/lab mix, strong as an ox and acts like a 100 lb. puppy, and was a stray. Animal control picked him up in a shady part of town and brought him to the shelter. He’s part of my family 100% but he’s a runner. If the backyard gate is cracked an inch he runs, if the front door is open to bring in groceries, he runs. He just really likes to roam.
I’ve had complaints from neighbors, animal control and my wife about him. I can’t even think of getting rid of him. We just have to be very aware about open gates and doors.
We even tried the invisible fence route, it doesn’t phase him. I guess the stray in him wants to be free!
