TL;DR: Puppy teething is a normal developmental process occurring between 12 weeks and 6 months of age, and minor gum bleeding is usually a low-urgency issue. Seek veterinary care only if bleeding is heavy and persistent or if your puppy stops eating and drinking.

What should I know about the puppy teething process?

Just like human babies, puppies go through a teething phase where their 28 deciduous (baby) teeth fall out to make room for 42 permanent adult teeth. This process usually begins around 12 to 16 weeks of age and concludes by the time they are six months old. During this transition, it is very common for the gums to become inflamed, sensitive, and occasionally bleed as the new teeth push through the tissue.

Is it an emergency if my puppy's gums are bleeding?

  • The urgency level for bleeding gums during teething is generally Low.
  • Finding a small amount of blood on a chew toy or seeing pink-tinged saliva is a normal part of the developmental process.
  • Medical intervention is rarely required unless the bleeding is heavy and won't stop.
  • Contact a veterinarian if your puppy stops eating and drinking entirely.

How can sending a photo of my puppy's mouth help with triage?

  • Allows a professional to confirm the gums are a healthy bubblegum pink color.
  • Helps identify signs of infection, fractured teeth, or foreign objects like toy pieces stuck in the gum line.
  • Helps determine if what your puppy is experiencing is standard teething or something that requires an in-person exam.

Clinical Context (Merck Veterinary Manual)

During puppy teething, oral behaviors such as mouthing and biting are common due to the puppy's need for exploration and play. While permanent teeth erupt, loose deciduous teeth can cause discomfort. Retained deciduous teeth are frequently observed in dogs, particularly small breeds, and can lead to permanent tooth displacement, malocclusion, or periodontal disease. Therefore, retained deciduous teeth should be extracted promptly, taking care to avoid damaging the underlying permanent tooth bud.
