thehappypup.com
Is a good site to go to that give you links to other places to find things, but for a good selection of gear, I suggest this
www.mr-s-leather.com/cat/1183-1382/.....pup-hoods-muzzles.html
And for a collar I like this site because you can fully customize one, color, material, studs, loops and so on.
collarfactory.com
I can vouch for the quality of collar factory and a friend of mine has gotten things from Mr.S Leather so can vouch for that site as well c:
Hope I helped a bit and hope you have if with whatever you buy ;3

You should ask um...  Rubberkitten He was mentioning something of the like from a guy he liked who enjoyed making custom masks.

https://twitter.com/BearDawgLeather i got mine from him. does great work and all custom hand tooled leather. lets your shit be unique and not just the run of the mill MR.S stuff

http://www.rubberdawg.com/ ??
oh, sorry, these are mostly rubber, as you would expect. I missed the "leather" on the first read.

No masks, but for other puppy play stuff, try http://shop.oxballs.com/DOG-POUND_c97.htm

Too bad you don't live here in TX. They have that stuff standard in most porno stores.

I hear the Bad Dragon website has some wearable dog cocks that you slip on over your actual cock

Mr. S Leather is good too. That's where I got my pup good ^^
