Yes, a thousand times, yes!
I just read a post in a community group that is equal parts familiar, and worrying.
The post was a new puppy owner, with a puppy that is not yet fully vaccinated. The owner was asking if there was anywhere in the local area that was safe for the to take out their new puppy, before their vaccination protocol was complete.
First Answer- No
Second Answer- No
Third Answer- Me, metaphorically jumping up and down and waving my hands in the air while I try to explain..
Dogs have a critical period of socialisation up until approximately 16 weeks of age and it’s quite literally- critical. Their brain will grow to 80% of its adult size during this time and experiences during this time have greater significance than at any other time in the dog’s life.
“By a critical period, we mean a special time in life when a small amount of experience will produce a great effect on later behaviour.”
— Scott & Fuller, Genetics and the Social Behaviour of the Dog
The risk of behaviour issues increases exponentially when a puppy is isolated during their critical period, and yet, this is still not only happening but being recommended to new puppy owners.
So, what can you do with your puppy before their vaccination protocol is complete?
1. Check with your vet whether an early finish vaccination protocol is an option for your pup. This could be the difference between your puppy being fully vaccinated around 12 weeks, or not until 16 weeks.
2. Enrol in a Puppy Pre School class in an indoor space (that can be disinfected) run by qualified trainers who understand what socialisation is- and importantly, what socialisation ISN’T. You can start in classes like this from 8 weeks of age, after your pup’s first vaccination.
3. Stay away from dog parks (for reasons that go beyond disease control), dog beaches and other high traffic dog areas.
4. Organise specific friends and family members to visit you and organise for you to visit them in their home. Diversity is important- expose your puppy to children of all ages, people who move, dress and speak in different ways to you.
5. Expose your puppy to noises, surfaces and novel items at home AND in safe spaces
6. Take your puppy out- carry them, hold them or sit them on your lap if you prefer but let them SEE the world you are going to expect them to be a part of for the rest of their life. They DON’T NEED to interact, but they DO NEED to observe.
I beg you to safely socialise your puppy. Their life depends on it.
