Grooming and coat
How do I remove tree sap from my dog's coat?

Short answer
A small amount of vegetable oil or peanut butter massaged into the sap for a few minutes breaks it down enough to comb out, followed by a normal bath to remove the oily residue. Trying to pull sap free while it is still sticky usually spreads it further and pulls out more hair than necessary.
Why oil works better than water
Sap is resin based and does not dissolve in water the way many other stains do, but it does soften and break apart when worked with an oil, since oil dissolves the same compounds that make sap sticky. Massaging it in gently and letting it sit for a few minutes before combing gives the oil time to work.
Combing it out safely
Once softened, a wide toothed comb worked from the outer edge of the sap patch inward usually lifts it free in small pieces without pulling excessive hair. Trying to comb through the middle first tends to spread the sap into surrounding clean fur rather than removing it.
Finishing up
A normal bath with dog shampoo afterward removes the oil left behind from the softening step, which otherwise leaves the coat looking greasy. For sap trapped very close to the skin in a curly coat, a small, careful trim is sometimes quicker and less stressful than prolonged combing.
Key takeaways
- Vegetable oil or peanut butter breaks down sap far more effectively than water or soap alone.
- Comb from the outer edge of the sap patch inward to avoid spreading it into clean fur.
- A follow up bath removes the oily residue the softening step leaves behind.
