I need to change Daisy over from AG puppy to the adult version, I'm also planning on swapping her natures menu to nature diet. Obv. as she has a sensitive tum anyway, I need to be very careful about how I do it. 1. Do I need to treat the adult version of AG as a new food and slowly introduce? or would it be OK to do a straight swap? 2. Is it a bad idea to introduce them both at the same time? I have about12 tins left of natures menu (which would normally be 12 days supply) and about 3 weeks left of the AG so was thinking about the following timeline. Introduce the nature diet over the next 2 weeks, gradually increasing the amount of nature diet & reducing the natures menu. Once I get 100% nature diet, then switch to AG adult over the next week (less time as it shouldn't really be a dramatic change) Does this sound OK?
