i understand bits your saying mate
the bulldog is peaked it’s a fine line between it giving everything and not having anything to give
if a hound ran 5 dead a winter a few long runs it will not be doing a lot for a few days mate just laid up resting this is when it can be hard to keep em right they can look rough after a hard day
i understand fat is used when running and glycogen is glucose ? better for replenishing after a stressful excercise? i maybe way out ? i’m more what has worked for me then the scientific approach
but it’s maybe why me dog does better and keeps
