Stitches win on security for deep, gaping, or high-tension wounds; skin glue wins on comfort and speed for small, straight, low-tension cuts.
The decision comes down to one question: how much pull is on the wound? Skin glue holds edges that already sit close on their own. Stitches hold edges that want to pull apart. That one variable explains nearly every recommendation below.
What Skin Glue Actually Does
Skin glue is a liquid adhesive that bonds outer wound edges, forming a film that sheds in 5 to 10 days. It is not a weaker version of stitches — it is a different tool for a narrower job.
DERMABOND PRINEO instructions state it is for easily approximated skin edges and should be used with, not in place of, deep dermal stitches. Glue closes skin, not the tissue underneath.
Where glue wins is comfort. Glue also skips the removal visit.
Where Each One Wins
Stitches hold better on wounds under tension, deep wounds, and areas where movement risks reopening. Glue works on small, clean, straight cuts with self-approximating edges.
| Wound Situation | Better Choice | Why |
|---|---|---|
| Small, straight, shallow cut | Skin glue | Edges sit together; faster, less painful |
| Gaping or deep wound | Stitches | Needs layered support glue cannot provide |
| Dirty or contaminated wound | Stitches | Requires cleaning and inspection first |
| Joint, leg, high-movement area | Stitches | Movement pulls glued edges apart |
| Paw pad, high-moisture area | Stitches | Glue is splash-proof, not waterproof |
| Surgical incision, low tension | Either | Cosmetic results comparable |
| Edges that pull apart on their own | Stitches | Glue needs edges that already meet |
What the Evidence Says About Reopening
Stitches carry lower risk of the wound coming apart; the gap is real but small.
A second Cochrane review on surgical incisions found sutures significantly reduced wound breakdown versus adhesives. Both reviews agree infection rates are similar in simple wounds and cosmetic results are comparable in low-tension areas.
On cost, the picture flips: adhesives may be more cost-effective for simple wounds because they skip anesthesia and the removal visit, though the adhesive costs more per unit than suture material. Some animals and people are allergic to adhesives.
Aftercare and Common Mistakes
Glued wounds must stay clean and dry for 5 days, and the adhesive must shed on its own — picking at it early is the most common way people reopen a wound glue was holding fine. Other mistakes: using glue on gaping, deep, dirty, or infected wounds; using it on joints where movement peels the film; forgetting it is splash-proof, not waterproof, so a bath or wet walk can loosen it.

Common Questions
Can I use glue on a wound that keeps opening?
No. A reopening wound signals edges under tension, which glue cannot overcome. It needs layered closure from a professional, not just surface skin. Trying adhesive again usually fails the same way.
How long does the adhesive stay on?
Tissue adhesive typically sloughs off within 5 to 10 days as the wound heals underneath. Do not remove it early. If it comes off before day 5, that wound needs a look.
Is glue less painful than getting stitches?
Yes, measurably. Stitches remain the better call when the wound actually needs them.
