The Case of Nong Tua-ngok: A Quick Guide to Wound Healing
"Nong Tua-ngok" (Bean Sprout), a Pomeranian and the oldest sibling of the Pom-Bangkaew gang, played a little too roughly with his younger Bangkaew siblings. This resulted in a wound right in the middle of his head, likely from a bite by one of the younger dogs.

Fortunately, once the wound was discovered, Nong Tua-ngok was promptly brought to Kwankham Animal Hospital Khon Kaen for a diagnosis within just one hour.

The veterinarian cleaned and examined the wound, finding it relatively clean and not deep enough to affect critical muscle layers. Therefore, the doctor decided to suture the wound closed immediately after cleaning it.

Normally, when animals sustain a wound, their bodies go through a natural Wound Healing process. This can be divided into 3 phases:

Phase 1: Inflammatory Phase This initial stage occurs immediately after the injury happens. It involves:

Vasoconstriction: The narrowing of blood vessels.
Platelet aggregation: Platelets clumping together.
Clot formation: Blood clotting alongside the response of various white blood cells.
Phase 2: Proliferative Phase This phase focuses on the rebuilding process, which includes:

Granulation: The formation of new connective tissue.
Contraction: The wound edges pulling together.
Epithelialization: The creation of a new skin layer.
Note: These processes typically begin 3-5 days after the injury occurs.
Phase 3: Remodeling Phase The final stage starts around 7-14 days post-injury and can last for months or even years. This is when the scarring process begins.

Why Suture? The Importance of the "Golden Period"
For Nong Tua-ngok, the doctor determined that suturing was the best course of action because the wound was clean, lacked necrotic (dead) tissue, showed no early signs of infection, and was brought in for treatment within the 3-4 hour "golden period." His wound is now healing nicely, and he is just waiting to have his stitches removed by the doctor!

Key Takeaway for Pet Owners: If your dog is bitten or injured, and the wound is clean and uninfected, bringing them in for prompt treatment within the 3-4 hour "golden period" means the vet might be able to suture the wound. However, if this window is missed, an open wound management approach can still be used to allow the injury to heal naturally through the three phases mentioned above.
