What is the difference between a toy and miniature schnauzer?

A toy poodle is a recognized breed of poodle and is the smallest sized poodle you can obtain that is recognized by the countries associated kennel clubs and according to show standards if you are planning on showing your poodle.

the 'Toy' category has no lower limit; tiny toy is still a toy.

Personally I don't think their is much difference in which poodle is better for you - it really depends on your own preference. As a lot of tiny toy and teacup poodles parents are runts of the litter size wise, it is always best to have both parents hip and eye tested before purchasing from the litter and also get written confirmation from the breeder that you can return the puppy within 14 days if a health problem is detected by your Vet.

This question is like asking if you should have a friend that is 5'4" or 5', one might be slightly easier to carry but that is probably the extent of the differences.

And remember, all pure bred dogs have the potential to be genetic messes, the more extreme the dog's look the more likely it is to have health problems.
