Oso is a 6 year old Golden Retriever/Sheltie mix male. Oso is house trained, walks well on his leash, and only weighs 32 lbs. Oso being of the herding breed needs a strong owner with no small children in the famly. If you are not consistent with him he will be hard to handle. Oso has been going to daycare and plays well with every dog we have introduced him to, he is handled in doggie daycare by both males and females and does well with both. Oso was rescued on his last day of life from animal control. We know that his previous owner was male and he does tend to listen better to males than females, but he can be a great dog for anyone who understand the herding breeds personality. This guy is super cute, and just a great little guy.
