I’ve usually use a fanny pack and a jacket with pockets to hold whatever stuff I need on a given day. I’ll put a tug loop through my fanny pack strap to hold that, and the ball, treat, and e collar can fit in the fanny and my pockets. I’ve seen some jackets with a magnetic insert for a magnetic ball, and I’d like to try that. All the pockets look great too. But I can’t find one I could see myself wearing, didn’t like the style I guess. For people who have tried a dog training vest - did you find it to be a useful thing? Do you always take it out to train with or just on certain occasions?
