Dog Owners - Need Your Suggestions

I guess I came in late here. We too just retired but we are now thinking our age may change what kind of dogs we get next. We are Aussie lovers. No better breed in my mind. Have had 6 of them. So last year when we got down to no dogs, we adopted/rescued 2 bonded girls that had lost there home. My first big peice of advice, RESCUE, RESCUE RESCUE!! Go to any rescue group or shelter and adopt a dog from there. We traveled all over the country with our Aussies, they were great. Actually or Jack Russell was part of that group and he was great too, but I' guessing thats to little for you. I think after the 2 girls we have now, we might go a little smaller. I've had a Springer Spaniel and she was wonderfull. They are a little smaller, and great dogs. But if I could endorse just one thing to you would be RESCUE A DOG, DONT BUY ONE. I can also tell you the mutts/mixes make some of the very best dogs you'll ever find.
