You would naturally up the calories altogether.
But to give you an example, when I have one drop a little wt or needs to add some wt, I simply add an additional chicken quarter in the morning and continue to feed as I have been in the evening. Splitting the feed seems to help some, but adding something in the morning does the trick for me. One of my favorite bitches is just a hard keeper for wt b/c she goes all damn day long. So, she eats a chicken quarter in the morning, one in the evening along with her "guts".

Meaux - good job on the feed my man. I got a good feeling about you and your dogs. You are getting into this right man.
