I've been taking my cocker spaniel to Cosmo dog park since he was just a few months old and I've always had very good experiences. He has lots of fun playing fetch in the huge fenced in area! Rylee can be a little stubborn sometimes and doesn't always like big dogs so I take him to the little dog area and he always does great. He loves to play in the water too, he just splashes around in it with his feet like a little kid. The only reason I didn't give the park five stars is because sometimes I question the cleanliness of the water in the pond.
