On the ecollar comparison chart, 5 tabs down it says Different Levels for Each Dog. What is that?

The tab labeled “Different Levels for Each Dog” is referring to a two dog model. Some manufactures make collars that are not able to adjust the correction level setting for each dog. For example, the Einstein collars are able to set two different levels. So, if you have one dog that needs a higher level of stimulation than the other, you are able to do so with the Einstein collars.
