That's ridiculous. Irresponsible of the kennel, no doubt ... but the OWNERS??? Holy.

I actually had some lady come to pick her schnauzer up from grooming. We generally have several schnauzers in the shop at once. She paid and heads over to a kennel to get her dog. I say, "Oh no, Ma'am, that's not Gidget. Gidget is over here." She actually argued with me, and implied that I was stupid and irresponsible to not know her dog! I had to actually take the other dog out of the crate and hold it up and say, "Ma'am, Gidget is a girl. This dog is clearly a boy." before she would take her own dog home ... and she was looking at both of them side by side.
