I found an indoor dog park like setting. They have 2 Rough & Tumble nights and 1 Gentle & Mild night. (evenings - 1 hour each) We took Daisy to the latter on Tuesday. She got along great with 3 young (5-7 mos) Whippets and 2 (1 yr) Beagle/Lab type dogs. It was a good experience for Daisy, me and son. Thursday, we took both Daisy & Duke to a Rough & Tumble. Also a good experience. The dogs were all mixes, but they were all young large sizes - playful in excess for Daisy's size. I ended up holding her 1/2 the time. Duke is not very socialized. The indoor park allowed Duke off-leash, thus less aggressive. He is not friendly at all on-leash. We need to go more often, expecially with Duke. The dogs there were regulars and knew instantly the new dog on the block needed a greeting. Duke was overwhelmed. He did bear teeth a few times. They supplied squirt bottles and a broom in case of a fight. I was nervous and totally expected to go home early. But, it's there for "socializing" and the dogs parents were OK with the way it went.
Curious - has anyone heard of an indoor park for dogs? The place is called Dunk-N-Dogs. A self-serve grooming facility that you bath your dogs and all supplies provided (stand-up tubs, dryers, etc.). The rear end (indoor park) of the facility is used daily as a Doggy Day Care.
