Although some vets recommend waiting until a puppy is fully vaccinated before meeting other dogs, new owners are also told that early socialization is key and that the ideal window in which to start socializing is when a dog is between three weeks and three months of age. It is impossible to follow both guidelines, but as long as you’re sensible and ensure that your puppy only mixes with dogs that are fully vaccinated, there is no reason that you can’t start to meet other friendly, sociable dogs pretty much as soon as you get your new dog.

What Is Socialization and Why Does It Matter?

New puppy owners are told to socialize their puppy, but what does it really mean? Meeting new people and new dogs is part of it, but that isn’t all. Socialization means introducing a dog to new situations, new people, new animals, and new encounters.

Having your puppy meet a policeman, in full uniform, for the first time won’t just teach the puppy that policemen in helmets and bright yellow jackets aren’t to be feared, but it will teach them that new situations aren’t a bad thing. The same is true of all other social situations. Generally, well-socialized puppies will do better when meeting new people and encountering situations as older dogs. Those who underwent no socialization will be nervous about new people and get anxious when put in a new situation.

Why Do Vaccines Matter?

Vaccines are also important. They protect against parvovirus, distemper, hepatitis, and rabies. Additional vaccines may also be given, according to factors such as the area your dog lives and whether it will be a working dog or a pet. After an initial vaccine, your dog will need to have an annual booster to ensure that it enjoys continued protection.

The initial vaccination requires two injections, one at around 8–10 weeks and the second 2–4 weeks later. This means that your puppy could be nearly four months old before it is fully vaccinated and has been given two weeks after its final jab.

In the meantime, if your puppy comes into contact with a dog that is shedding parvovirus, it could contract it. This leads some vets to caution against letting unvaccinated puppies meet other dogs.

You do need to be sensible. Don’t let your dog socialize with unvaccinated dogs, and ensure that you know the vaccination status of any dog with whom it comes into contact. This is the only way to be sure of your puppy’s continued good health while allowing it to meet new dogs and socialize with other puppies.
