Dog World: No nuts delight

We neutered our 5 year old American bulldog about a month ago, because we weren’t going to breed him, and we hoped it make him less of a threat to some other (more agressive) dogs.
The strategy seems to have worked, because he’s been having a great time in the dogpark and the local park down the street.
Went out today for what was supposed to be a quick walk and ended up spending an hour in the park as Winston gamboled with other dogs, mellow as can be.
This must be what it’s like when people’s meds kick in–the difference is not that obvious, but so pleasant.
