If you have a new puppy in the house, chances are your dog has probably changed its normal behavior. Maybe your dog is more active, eats more, sleeps more, etc. One interesting behavior change is that dogs tend to drool more when they see a new puppy. That will be the topic of our discussion today, as we cover all the reasons why dogs drool when they see a puppy. It is important to know that small amounts of drool is completely normal and natural for a dog. Dog’s usually produce drool in order to help them chew and digest food. 

Why do dogs drool when they see a puppy?

Dogs drool when they see a puppy because of excitement, nervousness, and stress. 

Excitement 

The main reason dogs drool when they see a puppy is because they are overly excited. This is the equivalent of your parents coming home with a newborn sibling. It is very common for dogs to drool in situations where they are excited. For example, a dog will likely drool from excitement when you walk to their food bowl or give them a treat. 

Nervousness 

A dog will also drool when they see a puppy if they are nervous. A new puppy generally is a ball of energy, and it can take a dog a while to adjust to the puppy. Puppies sometimes display erratic and unpredictable behavior, which can cause a dog to get nervous and then drool. Dog’s are also animals of habit, so even minor changes in their environment can cause them to be nervous and drool. This is why it is common for dogs with separation anxiety to drool whenever their owner leaves them. 

Stress

Finally, a dog might drool when they see a puppy because they are stressed out. Perhaps your dog is used to peace and quiet, and a new puppy certainly interrupts that zen. It is very common for dogs to drool in stressful situations. This is why they will sometimes drool when they go to the vet, or drool when they have been in a car for a long period of time. In extreme cases, a dog will become so nervous that they drool and then throw up?

Should you be worried if your dog drools around puppies?

No, most of the time it is completely natural for your dog to drool around puppies. It will most likely not last very long, and there are usually no other changes in behavior. However, if the drooling continues for days, and you notice other changes in your dog’s behavior, then there might be a medical issue. If you suspect this is the case, you should contact your vet immediately.
