iHeart you and people like you. I do not heart people who are growled at by dogs.
Sometimes Pura will mention dog walking when we rabbit hole what we'll do in England when we get back. I've waited nearly 9 years (and counting) since my last GSD so I'll be swamped. Her name was Rook.
There's quite a few dog walking / dog sitting / dog bathing type apps in case you're unaware. Plenty of dogs would love to have your attention. Check it out, iHeart dogs so much I get all soft like this and don't even curse or anything and make gif's.
Gosh Dan...your soft side makes me melt.
I know those apps but I'm happy to have found an official assignment with a regular pay. Often those app walkers are self employed or unofficial. I have at least a bit of a security if something would happen being employed.
If Pura is into dog walking then go ahead! It doesn't have to be the big ones or youngsters. Even old dogs appreciate someone taking them out and then it is not as stressful in the beginning.
