Male Rat Terrier to be rehomed

We are looking to rehome our 18-month-old male Rat Terrier. He is still intact and is very well, and he has proven to be effective. He is very loving and friendly, but he is also very energetic. He enjoys being outside and is very good at catching mice and keeping varmints away from the property. He grew up on a farm and is comfortable around cattle and other livestock. Our female just had a litter of puppies, so we're hoping to raise a couple of them without worrying about being bred too soon. Please call or text if possible.
