Oh 'piece of string' question
Ok - will do my best. The official line is 'yes' reduce the normal food ration roughly by the same weight as you are using in training treats. If you feed kibble you can actually use the food allocation as training treats - just remember to do your training before meal times when pup is hungry
Having said that I dont reduce Dills rations as I'm trying to put weight on him, but Daisy is a bit of a porker so I do reduce her rations
Does that help??
Also - just another thought - its better to do the training in short bursts of 5 -10 mins 3 times a day rather than half an hour in one go
