Well...we got a two year old golden retriever. He is so beautiful. He is very calming and doesn't really play. He prefers to lazily walk through a bush or paw at the water. My daughter is taking some time to get used to him. He is 90 pounds so he is a big addition to our family. Yesterday she held his leash all the way to the store and back! It is a real help as she needs to start walking without holding onto me.
I don't have a service dog but I would love to hear about yours if you would like to share.
