Do dogs mouths bleed when teething? Here’s What to Expect

Abnormal tissue tends to be easily damaged, not only because it sticks out but also because it’s often quite fragile. It also heals slowly. Therefore, any investigation of unexplained bleeding from the mouth should also include a thorough search for a mass.

The correct name for gum disease and bad teeth is periodontal disease or periodontitis. It’s a destructive process that starts with plaque building up at the junction between tooth and gum.

A cute and totally normal reason for bleeding in the mouth or gums is teething. Loss of the baby or milk teeth occurs gradually between 3 and 6 months of age, like this:

It’s no big deal. We can sometimes fish them out awake, but most of the time a quick anaesthetic is on the cards.

Puppy teething timeline

The teething stage doesn’t last long, and before you know it, your puppy’s baby teeth are gone and your adult dog has a full set of new chompers.

  • 2 to 4 weeks: Baby teeth come in. Puppies are still nursing at this point – their eyes are opening, and they’re beginning to explore the world beyond their mother.
  • 5 – 7 weeks: Baby teeth finish growing. Puppies will naturally nip each other and chew everything around them as part of an important stage of their development.
  • 12 – 16 weeks: Teething begins as baby teeth fall out. This process can take as long as a few months, though it depends on the individual dog.
  • Puppies typically have all of their permanent teeth by six months of age. All dog breeds have about 42 adult teeth in total – perfect for a lifetime of ball-catching, stick-chewing, and treat-chomping.

    My children like playing rough with the puppy, and they say that they don’t mind the occasional scratch or gentle bite. Is this okay?

    No! Permitting this behavior teaches your pet that hands are acceptable toys to use as he or she pleases. Your dog is not only learning that it is okay, but the pup is even being rewarded for this behavior when your children continue playing after being bitten or scratched.

    Bleeding Gums in Dogs | Wag!

    Have a look at the picture above. You could be forgiven for thinking that Barlie’s gums are just the result of a good chew on a bone. But hang on: why are there red spots a long way from the gumline and even on the tongue?

    The answer is a disease you won’t easily find if you look up the causes of bleeding gums in dogs. Even though what Barlie had could have killed her.

    There are five reasons you might see bleeding from the mouth and gums. I’ll run through the four simple ones and get to Barlie’s last.

    The correct name for gum disease and bad teeth is periodontal disease or periodontitis. It’s a destructive process that starts with plaque building up at the junction between tooth and gum.

    Plaque is really just a biofilm containing bacteria so you can imagine how the immune system feels about that. The result is gingivitis, which causes the gums to bleed easily, especially when probed or brushed. Without treatment, attachment loss and pocketing lead to tooth loss.

    Periodontal disease is easy to identify by the red gums, the smell and the brown buildup of mineralised plaque called tartar on the teeth. However, that’s not Barlie’s problem. Just look how clean her teeth are from chewing bones!

    A cute and totally normal reason for bleeding in the mouth or gums is teething. Loss of the baby or milk teeth occurs gradually between 3 and 6 months of age, like this:

    The pictured deciduous canine tooth crown was found by a puppy owner after she saw drops of blood. The missing root is totally normal: it’s been destroyed by the advancing adult canine. In a few days a new tooth will emerge from the hole.

    Abnormal tissue tends to be easily damaged, not only because it sticks out but also because it’s often quite fragile. It also heals slowly. Therefore, any investigation of unexplained bleeding from the mouth should also include a thorough search for a mass.

    The picture shows a small benign growth called an epulis that got knocked and started bleeding. You can read a lot more about mouth lumps in dogs here.

    Anything that gets caught in the mouth (especially between the teeth) can cause bleeding. Usually it’s a small piece of bone, but I’ve also seen pieces of plastic or aluminium from chewing up containers.

    It’s no big deal. We can sometimes fish them out awake, but most of the time a quick anaesthetic is on the cards.

    The most common bleeding disorder in dogs after rodenticide poisoning is a low platelet count. However, whereas bleeding from rat bait is usually internal and hard to spot, bleeding from low platelets has a characteristic pattern.
