Before you head to the dog parks, leash him up and take him, several weeks, on a dog-food shopping trip to PetSmart, PetCo, Pet-whatever store. That's the easiest place to start.
I had to start letting Vi out hr gargle door. The paver are already to hot. She can make it o he bk through the boarders.
They do go thru changes, and not when you expect it. These 2 went thru major changes as they got older (after 1 year)
my dogs tend to run back inside when it's hot out. do you think it could be that? Sarah
