Updating to add a heads-up to anyone who takes their dog to play in the pond at Cosmo. We took our dog to the vet and found out that she has Giardia, which is an intestinal parasite that is most commonly transmitted through feces contaminated water. Our dog is now taking meds and will be retested in two weeks. Our vet says she usually gets at least two cases a week from dogs that play in the pond at Cosmo. I'm still giving Cosmo 5 stars because it's awesome, but we will be playing only on the grass side from now on. (Don't worry...we will be keeping our dog home until she gets a clean bill of health from the vet!)
