This morning he growled and snapped at a dog that he's known for almost a year and the two of them have always had positive interactions in the past. The dog is a German Shepherd and is an intact male, both of which are things that seem to be new triggers for Finn. He did have a nice romp with a seven-year-old GSD female named Bella later in the day, so it really might just be the "intact male" part that is an issue.
We've also had to put him the in "penalty box" at the dog park quite a few times recently. He loves it there and he's great friends with most of the owners and the dogs but he's been misbehaving a lot and we're really not okay with some of the things he's been doing. The "penalty box" does seem to work well for most of his indiscretions but there have been a few times that we have just taken him home early. We really want him to behave well at the dog park because he gets such good exercise and socialization there.
There are a lot of dogs around Finn's age at the park so almost everyone had stories to contribute about the bad things their dogs have done. While it's nice to know that we're not alone and that everyone still thinks of Finn as a friendly, gentle dog, we have to watch him so carefully because he is just so big. He can make the same mistake as a smaller dog but his mistake will likely have greater consequences.
We are lucky that we live close to this awesome park with lots of amazing calm, friendly and forgiving dog owners. We've seen dogs pee on people, knock people over, get into tussles with each other, nip, wrestle and pin each other, and yes, grab at clothing or hands with their mouths. For the most part, everyone tries to help each other out with advice, separating dogs, reinforcing boundaries and rules, watching one dog if the owner has to attend to another dog, and just generally being great company. And all our dogs have good and bad days, and people are really good about calling it a day if their dog is acting out.
I am hopeful that Finn is just going through his adolescent phase a little late due to all the upheaval he experienced in his early life and that soon he will go back to being the super friendly, gentle giant that he's known as. I feel that we keep a close eye on his behaviour and are able to spot when he's about to get testy, and I know that we have a pretty good handle on his triggers. We just have to be patient and firm with him and put in a few extra hours of training.
They calm down around three years old, right...?
