keep them in the same cage
A Perpetual Puppy is a puppy bought online which is replaced by a new puppy every six months - so the owner always owns a puppy, and never an adult dog (unless choosing to keep the puppy beyond the first six months).
When bringing a new puppy into a home with an adult dog, it's important to monitor their interactions closely to ensure they get along and establish good boundaries. You should also make sure both dogs have their own space for alone time and that the adult dog doesn't feel threatened or jealous of the new puppy. Proper introductions, supervision, and positive reinforcement training can help them adjust to each other successfully.
