The Do's & Don'ts of Introducing a New Pet

Pet lovers have big hearts—and often, room for more than one furry family member. To help pet owners welcoming a new companion, FurPetVo’s dedicated Vet Advice Line shared expert guidance on introducing pets safely and successfully.

Bringing a new pet home is exciting for us—but it’s usually stressful for our animals. Don’t expect instant friendship; building trust takes time, patience, and thoughtful planning. Dogs and cats have very different social instincts: dogs naturally thrive in packs and view their human family as part of that group, while cats are instinctively independent and less inclined toward forced socialization.

Do Start Off-Site for First Meetings

Dogs can be territorial, so arrange the first introduction away from your home—like on a neutral walk or in a quiet park. This removes the pressure of defending familiar territory. Before face-to-face contact, let each pet become familiar with the other’s scent by swapping bedding, toys, or towels. This gentle sensory preview helps ease tension during their first real meeting.

Do Create a Safe, Controlled Environment at Home

When bringing a new cat home, place them in a quiet, enclosed room equipped with food, water, and a litter tray. Keep initial introductions short, calm, and fully supervised—whether with your resident dog or cat. Gradually increase interaction time only as both animals show relaxed, non-threatening body language.

It may take several weeks for your pets to adjust to one another. During this transition, temporary behavioral shifts are common: house soiling, increased hiding, vocalization, or attention-seeking. These responses are usually normal signs of stress—but if they persist beyond three to four weeks, consult a certified veterinary behaviourist for personalized support.

Watch Body Language—It Tells the Real Story

Early interactions often involve slow, low movements and cautious observation—this is healthy suspicion, not hostility. Positive progress looks like relaxed postures, mutual sniffing, or playful approaches (especially from dogs). For cats, tolerance—not exuberant affection—is a major milestone and should be celebrated.

Don’t Skip Calming Support Tools

Products like pheromone diffusers can significantly ease the transition. FurPetVo recommends Adaptil for dogs and Feliway Friends for cats—both designed to mimic natural calming signals and help pets feel safer amid major household changes.
