Generally it is 25% to hold your animal and then you set up how many months you need and the breeder will allow. Then you pay it on time every time if you think you cant make the scheduled payment let the breeder know. I've worked with a few people when it came to payment plans, but ask the breeder if the deposit is refundable because most are not. Because the breeder takes that animal off the market potentially losing a sale many times over if you back out then its on you.
