My Yorkie does agility for 4 years now.
The rule is no agility until their growth plates are set and no longer growing.
Start with basic obedience during this time.
Agility can be demanding on the knees and back, however, agility dogs Are real athletes and in great physical condition.

That all being said, you don't want yourmpupmto be crippled from the activity. After the LP situation is taken care of you will need to ask the surgeon if they think agility would be OK for your pup - then watch for any issues that might come up.

I hate the name, but there is TDAA, Teacup Agility Association of America, that is for dogs under 20 pounds and uses smaller contacts/equipment. However they compete by jump height in any competition, be it CEP, NADA, or AKC. They will be officially measured at their first even to determine jump height. TDAA has a controversial thing going on right now where you can pick the jump height you want your dog to jump - good for smaller dogs, and older dogs - but tends to make others less respectful of TDAA.

MOST IMPORTANT is if you and your dog are having fun!!!! So....do obedience now, then take a beginners agility class and see how you like it. You do have to protect those joints though.
