I am not a fan of TOTW because it it made by Diamond and they have a big recall history. If you shop at the big stores like Petco and Petsmart, I would consider Merrick Grain Free, Wellness Core, and Nature’s Variety Instinct. I fed my Dane a rotation of different foods including: Acana (Grain Free), Earthborn Holistic (Grain Free), Go! Fit & Free (by Petcurean), Horizon Legacy, and Annamaet (Grain Free). My Dane is a picky boy when it comes to kibble so I was somewhat limited. Other brands I like but he didn’t: Fromm (Grain Free), Nature’s Logic (has smaller kibbles), Orijen, Evanger’s (Grain Free), and Zignature (Grain Free). I would recommend going through the 4 and 5 star reviews to see what you like and what may work for them. If you want to try one of the brands that aren’t carried in Petco/Petsmart, I would get it online from chewy.com or petflow.com.
I know you want to get her off TOTW ASAP so you don’t want to gradually mix in another food. The faster you switch the more likely she is to have some GI upset like diarrhea. To try to avoid that, you can add a tablespoon of canned pure pumpkin (not pumpkin pie filling) to her new food- that will help with the diarrhea because of the fiber. I would also get digestive enzymes and probiotics and add them to her food to help with the switch.
On another note, your GD rescue that is 7 months old should still be on a restricted calcium/phosphorous food for slow growth. See this list for large breed puppy appropriate foods: https://docs.google.com/file/d/0BwApI_dhlbnFTXhUdi1KazFzSUk/edit?pli=1
Luckily, the NV LID Turkey is on there.
Good Luck! And please post any other questions you have. Hopefully we can help! 🙂
