The swap usually happens in the last few months of your dog’s puppyhood, at around the time when he stops growing which tends to be month 8 and onward for the Labrador and Poodle hybrid. Use the water trick mentioned before with the gradual addition of adult kibble into his puppy one to allow both him and his digestive system to adjust to the change slowly rather than all at once and risking an upset stomach. You can use the same method later down the line when he turns to his senior years, or if you’re looking to get him onto some new food in general.
