I would get a nice harness for protection work, Bridgeport equipment has the one many seem to have, I really like mine and Karlo has worn it since 4 mos, hasn't grown out of it at 90#(I think I have the medium): https://www.bridgeportequipment.com/...x?productId=96
It is called a tracking harness, but I don't use it for tracking, just protection work. When Karlo sees the harness he gets all excited.
Puppies don't need much as far as equipment, so I wouldn't worry about stuff for his smaller size, if you need something for training you could borrow from a club member. He'll outgrow it before you know it. A flirtpole/rag or burlap on string for tug/prey work, balls on string, tugs will be needed for the pup.
This is what I use/carry weekly:
A tracking line(ASAT), fursaver, agitation collar, prong collar, travel crate, water bucket-gallon jug water, crate fan, gloves for protection work, muck boots, raingear, training vest, tugs(I like the synthetic two handled tugs) balls on string, short tab leash, lightweight training leash, heavier long line for agitation work, camera, tote bag for all your gear!
The sites I use most are HallmarkK9(vest
, leashes/lines, tugs, balls), EliteK9(agitation collar
), Clean Run the other stuff, I just googled for best pricing or shopped locally. I also got some trail shoes with short cleats for the protection work, gives me better traction.
Most of these things you can purchase along the way, you won't need the agitation collar for a long time, I like the one I linked better than leather, but others at your club will let you know what they prefer on equipment, and sometimes clubs put together orders for discounts.
