Hi, Thanks for taking the time to read my post! Recently, I had my 14yr YOUNG Shih-Tzu to the vet because she was acting weird, not her normal self. For no apparent reason, she would just get up and quickly walk around the house in a circle. (Not chasing her tail-circle), more like, confused and scared, and seemed to be wanting to get away form a possible bad dream she had. They checked her out and found her to be healthy. and as usual, nothing wrong at time of a Dr Office Visit. (lol) This behavior happened at random times, maybe 4 times in the past month or 2, enough to warrant me to have her checked. I Googled her symptoms and found it to be similar to Dogie Dementia or Canine Cognitive Dysfunction. Although she wasn't diagnosed with any of these, the Vet suggested I give her Neutricks: http://neutricks.com/ and Purina Pro-plan BrightMinds https://www.proplan.com/dogs/platforms/bright-mind She currently has been eating Wellness Complete Health for Senior. When I went to local pet store to get Purina, the cashier told me that Wellness is better than Purina. My Questions are: 1. Is Wellness better? 2. If so, Can I just mix the 2 so she gets best of both worlds? 3. Is it better to keep her on her current food, and just give her the daily Neutricks treat instead? I have read reviews on both of the new items and seen a lot of Very Positive reviews. I just don't want to take away form any good that I am currently doing. Side note: I am aware that I have to mix any new food I give her with her current food, to gradually change it. Thanks again!!!!
