Try to find local pup groups, see if they do meetups and moshes.

Pup play is what you make of it; you dictate what and how much of you do.

As for gear, there is nothing required. Helpful to wear kneepads and padded gloves if you plan to get on all 4s. If you want a pup hood eventually, there are loads of merchants and brands nowadays. Mr S leather, mistr bear, forfun, furrjoi, wruffstuff, scrpyard leather... Find a style and material that is comfortable to wear and affordable for you. Do consider wearing contacts or some kind of sporty glasses when wearing a hood.

Physically, the only thing that would need any kind of prep is a tail buttplug, and you'd want to be clean for that, lol. For Pup hoods you'd want to take off any jewelry that would get in the way. Get contact lens or glasses that you feel comfortable fitting around the hood, or through the eye holes. If you plan to do any pup mosh, try to avoid wearing anything pointy so you don't poke others or their gear. This can include anything with a buckle (like cuffs) that have pointy parts in the buckle. Thats the main advice i can think of for pup play specific gear.

Hehe, thank you, woof~ Alas, findom is not one of my interests. But I do enjoy pup play mixed with other forms of domination
