I need some ideas for a dog fundraiser
Of course! You have every right to feel confident in your own body no matter what anyone else says!
get some animals for people to adopt
a dog show, dog walking, dog grooming, meet and greet (spell it MEAT)
Either a fashion dog show, trick dog show,etc., and use the dogs you want to raise money for.
Depending on where you live, you could do a dog wash where you wash peoples dogs
car wash maybe??? or a garage sale
Charge to use the fire hydrant
