It is possible to potty-train your Cavapoo puppy during winter. Cavapoos are unaffected by the cold because their thick-layer coats provide warmth and regulate temperature. Some have found winter an excellent time to potty-train a Cavapoo since there are fewer distractions outside and the puppy gets to business on time. Nevertheless, keeping your Cavapoo puppy out for too long is not advisable, even though it can withstand colder temperatures.
