How do you keep the rubber tubs/touch pads from collapsing under the weight of the dog while you are using it for training?

Hi Cindy,

I was wondering, how do you keep the rubber feed pan from collapsing under the weight of the dog? I purchased the rubber feed pan to teach rear end awareness. Every time my dog stands on it it collapses. In the videos you produced on the subject. You use the rubber feed pan but it does not collapse. I have resorted to several cut up 2x4’s screwed together. It works but is a headache. I figure you must have done something similar. But perhaps not so cumbersome. I would appreciate it. If you could let me know exactly what it is you're using.

Thanks.
