We have a 6 1/2 year-old Goldendoodle named Honey and a 15 year-old Chihuahua named Sassy.
Goldendoodles are a mix of two of the four smartest breeds (poodle and golden retriever). While mischievous, Honey is a terrific dog and brings a lot of fun to our family.
Sassy is slowing down with age but we have come to really like Chihuahuas too. They are not good with the snow but are intelligent and friendly.
