How Much Should A 6 Week Old Toy Poodle Weigh When Grown?

There isn't a set weight that a toy poodle should weigh at any age (unless your pet is obese - then you will be given a target weight). To be considered a toy (according the the AKC) he/she much be no more than 10" tall.
The best way to guess how much your poodle will weigh is to find out how much the mom and dad weigh.
