I always have done the puppy nesting thing and wound up giving a lot of it away lol
Things I did use, out of the oh 40 things that I bought for the puppy- puppy stage stage that I actually used during the puppy-puppy stage:
Flirt pole with fleece and leather flaps on it
Bowls for training position (rubber kind from tractor supply) for a whopping 2 weeks or so. Should have stuck with that though. My bad.
Little flat collar and light lead
Puppy harness for playing flirt pole w/decoy
Multiple dish towels were sacrificed as tug toys. Never unattended though
Treat pouch and Bandaids for my fingers for the using food stage of puppy/young dog training
At 4 to 5 months I added/started using:
Nylon slip collar (leash reactive)
Leather agitation harness for bite work
regular flat collar
6 ft 3/4 leather lead
Light long line
Light thin leather puppy tug
At 6 months I added pretty much rest of things I use for my grown dog:
And I also got him a nice personalized nylon webbing 1.75 inch flat collar that has an inside hidden strap that will accommodate an ecollar. I don't use one at this time, but there was no price difference between the one that had the hidden strap or not. And the inside strap in not intrusive in any way. It will be his final collar since it adjusts 19" to 25"
I also have stuff for IGP like articles, IGP1 dumbells, chalk for marking corners, tracking flags. Fans for my truck for hot training days. Non spill bowls for water in the truck/crates. Oh, and I always carry a good person AND K9 first aid kit. And recovery electrolyte powder for their water for hot days when I work them.
Hmmm, let's see...for the puppy chewing phase-he never got into Kongs- the ram horns worked well. I still have them laying around and have been meaning to look into their impact of wear and tear on adult teeth. I brought them in for the pup, and Valor wound up loving them..and the puppy now has adult teeth but still likes them. I don't like marrow bones for that reason- wear and tear on teeth, but horns are hair..still do need to read up. I am not a huge fan of fostering, in adults at least, the need to chew recreationally for periods of extended time in any event. I am not totally against it, but I do like when a dog can settle without occupying themselves with chewing.
I don't use a vest either for OB. I have no issue with them but to me it is just one more thing to phase out. I stick stuff everywhere. Good pockets help a ton. In hot weather as gross as it is I have slimy tugs and balls jammed in shirts, back of bike shorts lol I once had *someone* at a seminar tell me I had lettuce from lunch stuck on my chest..but it was grass from keeping my dog's tug in my shirt lolol Oh and a few weeks ago I fell asleep overnight with an article stuck in my sports bra. Ready for the track!!! lol
For toys the Tuff Kong "rope inside a toy animal" (non stuffed) work for us. Any toy really, no matter how much it is for "power chewers", is time stamped around here. They play rough with it, I keep an eye on their condition, and toss when they start to lose stuffing or tear. The dogs usually stop engaging each other and/or me with them once the toy is about to die. When they settle in on the floor and get all comfy to really chew it, that is my clue there has been a breach lol My dogs do like Jolly balls as well. They last a bit before someone rips a handle off, and then they are still good after you trim off the remaining handle. Oh and those super tough black tires stand up for a while, if you stay away from the cheap ones.
I'm sure I forgot stuff I have bought and currently use lol But hope all the posts here make you think of fun things to buy. I LOVE buying things for dogs. I have to discipline myself hahaha
Enjoy the tortuous nesting period
