switching foods the right way

Hey everyone...well I decided to switch food. Boomer just wasnt really eating his Eukanuba. I decided to go with the brand Wellness. So I mixed the food with like 25 percent Wellness and 75 percent Eukanuba. Is that how you graduallly mix...eventually work up to 100 percent? If so what do I do if he just picks out the wellness chunks and wont touch the eukanuba bits? I dont want to just give him straight wellness incase it might cause him to have the runs, but if he wont touch the eukanuba now what do I do? Hope someone can give some advice....I just dont want Boomer to get a tummy ache. Thanks for taking the time to help me out.

 

Thats the right way to do it, another thing you could try is is adding warm water to the food, let it soak for about 10 minutes until its soft and cooler, it'll be harder for him to pick out the new food.

If Boomer has already had a few meals were he's just picked out the new food though and he hasnt got diarrhea then he may be okay to just switch over fully to the new food.
