Cali and I do agility, too - keeps us on our toes
She is always the smallest because ALL the other dogs are really big, but it doesn't really bother her though because she has never been in a class where they had small dogs.
As long as she enjoys it we will keep going. She is getting ready for her first trial competition in about 3 months.
They have something called teacup agility - have you seen that? We went to watch one and the dogs were about 10 to 20 pounds - Cali is 3.5 so we still did not see it as toy dogs
