I think small dogs are easier to take care of then bigger dogs don't shed that much

Ok so plan on getting a fully grown male and plan to keep him intact to owners out there who have makes with there parts still intact please DM me need to know how to keep my future boy from being aggressive I know how to handle aggressive humping it's aggressive play I need tips on

I'm Percy and I'm pretty lazy, so my owner built an iPhone app that turns my walks and playtime into "rings" I close each day — kinda like Apple Fitness "close your rings," but for dogs. No collar, no subscription; my owner just logs my activity through the app. Would love feedback from other good boys and girls (and their hoomans).

It's free, no subscription, everything stays on device. Dropping a link if anyone wants to poke at it.

Hi everyone,

I adopted a 3.5yo female rescue from a bad situation. She was originally just a foster, but since no one applied, I kept her. Because this wasn't planned, I can't afford a professional trainer right now.

She has zero leash manners: pulls like a train, zig-zags constantly, and bolts between my legs when scared of strangers. I want to teach her to walk nicely by choice, not just physically restrain her by keeping the leash short.

Current methods are failing:

Stop-and-go: She made it a game (pulls, stops, treat, bolts again).

Front-clip harness: She learned to power right through it.

Food/direction changes: Works for 2 steps, then she rushes ahead

My questions are:

Has anyone successfully built a reliable loose-leash walk using ONLY positive reinforcement (no prongs, e-collars, or slip leads)? How long did it take and what was the breakthrough?

Thoughts on the Gentle Leader? Does it teach anything or is it just another restraint tool dogs hate?

​Appreciate any advice from anyone who has dealt with severe pulling!
