My favorite toys are the big 3" wide by 12" long firehose tugs with two handles from K9ops but the last two I've gotten both leaked dye, no good. I do like their rubber tug balls and the extra large foam balls on a rope from Starmark.
The 6' long 3/4" wide (they're actually 5/8") leather leashes from Leerburg are the nicest I've found. I don't use these for training, they're my nice, leather, taking a walk, leash.
Once my dogs are grown I like to get them a high quality 2" wide leather collar that matches the leash. Leerburg has nice leather collars too.
For affordable, rugged training collars it's hard to beat canine athletes IMO. Great collars. Big selection too. Of course for prongs, slips, and fursavers nothing beats Herm Sprenger.
I own a really nice harness for agitation work and for the life of me I can't remember where I got it. I think Ray Allen Manufacturing but I don't remember.
There's a ton of other places with great products too but these are the shops I frequent the most.
