Are Contracts common for the sale of Shelties?

The breeder will probably request a contract be signed, stating that the puppy will be spayed or neutered when it reaches the appropriate age. REMEMBER, the responsible breeder only wants the best possible specimens of the breed to contribute to future generations, so you should be willing to accept this agreement if it applies to your puppy. Spaying or neutering your dog also decreases the risk of some future health problems.

Contracts also often cover health conditions that may arise in the puppy over time, or "First Right of Refusal" where the breeder is able to get the puppy back should the owner no longer be able to care for (or want) it.
