Meet Luigi! An 8 week old male rat terrier and border collie mix! Yes, it’s true! His mom is a small rat terrier and we believe the daddy dog is a border collie. There are 5 puppies in his litter, two males and three females. All extremely sweet and loving babies! They currently weigh between 6 and 8 lbs at 8 weeks of age. We believe they will be medium in size. A wonderful group of siblings ❤️❤️❤️
