I have this and I LOVE it.
Pet Gear Blue Pup-Tub at PETCO
I got a good price on it but I can't remember where. Right now Petco is having a good sale. It has clips on BOTH sides so they can't go over either way. Drains well. Margaux is doing well with it. I can put it on the kitchen counter. Angel on the other hand, not so much. I have worked with her but she still goes crazy. For her, I put it in the bathtub but on a large plastic storage bin turned upside down. Works great. Also good for doing nails or clipping when you really need them NOT to move. I have a grooming table but that they can wiggle around on.
