Any dog can become reactive, but it’s more likely to occur in dogs over one year old than in puppies. Genetics, previous traumatic experiences and lack of appropriate socialisation as a puppy are some of the risk factors.

Often reactive dogs are fearful dogs, and if the early signs are missed, this can escalate to aggression, such as biting and snapping. Medical conditions such as pain can make reactivity worse, so it’s important to seek advice from a vet for any reactive dog. The good news is, many reactive dogs can be retrained over time with the advice from a qualified behaviourist and owner dedication.

When is reactivity normal in dogs?

There are some situations where dogs look like they are reacting but it’s actually normal behaviour. Observing their body language and getting to know the early warning signs when your dog isn’t feeling comfortable is key.

Playing

Dogs are sociable creatures and often love to play. However, play behaviour can look similar to aggressive behaviour. It can also lead to aggression especially if the dogs are different ages, energy levels or sizes. Short supervised play sessions with dogs of similar energy levels can help. Older dogs are less likely to want to play especially if they have arthritis, pain or problems that can lower their tolerance threshold.

Puppy biting

Puppies love to play and explore the world with their mouths. This means they like to bite and chew and this can often be on furniture, hands and legs. Teaching your puppy to redirect chewing to appropriate chew toys such as puppy Kongs can help. Speak to a Joii vet nurse for more advice on this.
