My current pup is almost 18 months old. Right around the time we started trusting her a little and leaving her out of the crate when we went out briefly we had an issue. A pissed off puppy! We have a rough routine, and the dogs generally get a trip to the park late morning. Well, I had something to do first, and it was too hot to take them. The park would be next.
When I got home I found our bedroom carpet not only shredded at the threshold, but she had torn it away from the tack strip revealing about a third of the room. She was determined to get her damn energy out! She’s much better now that she survived that event. I love them to death, but they also need a healthy fear. She was a slow learner, but we made a deal and she’s going to make up for it with sweetness.
