I went through much the same thing when we got our puppy-and it can drive you crazy! Using the parameters I learned from those on this forum(who actually know what they're talking about) I chose to go with the BB Wilderness, salmon flavor. Just the regular adult, not large breed. I have been really happy with how he's done on it-it has worked very well for us. I know nothing of the Verus to be of any help. Just know what has worked for us. Good luck and there are many more on here with much more knowledge that can probably weigh in on the other brand.
