How to Get the Dog Smell Out of Blankets — Without Just Covering It Up

If a dog blanket still smells after a wash, the odor almost never left in the first place — it got rinsed down and diluted, then came back the moment the blanket picked up any moisture again. That "wet dog" smell comes from bacteria and yeast living on your dog's skin, which produce compounds that only turn pungent once they mix with water. Regular detergent, run on a quick cold cycle with a squirt of fragrance, cleans the surface but often doesn't fully break down what's underneath. Fixing it takes three changes: an enzyme-based detergent, warmer water, and a full, thorough dry.

Why the smell keeps coming back

According to the American Kennel Club, the smell most people call "wet dog" comes from bacteria and yeast that live on a dog's coat as a normal part of their skin ecosystem. Those microbes give off compounds as a byproduct, and moisture is what releases them into the air — so a blanket doesn't have to be dirty to smell, it just has to be a little damp. That's also why a blanket can come out of the dryer smelling fine and then smell "off" again a day later if it sat somewhere humid, or if your dog napped on it before it was fully dry.

This matters for how you wash, not just what you wash with. A fast, cold cycle with a heavily fragranced detergent can leave a blanket smelling good right out of the dryer while doing very little to the bacteria and body oils actually causing the problem — the fragrance is just outcompeting the odor, not removing it.

The actual fix

1. Shake or vacuum off loose hair first. Hair trapped in the weave holds onto skin oils and slows down how thoroughly detergent can reach the fabric. This step is about odor control, not deep hair removal — for the actual buildup of hair in your wash, here's a separate breakdown on getting pet hair out of laundry that covers it properly.

2. Don't overload the machine. A stuffed drum means water and detergent can't fully circulate through a thick blanket, which leaves oils trapped in the middle layers — the exact spot where odor sets in and stays.

3. Wash warm, not a quick cold cycle. Warm water helps an enzyme-based detergent actually break down the proteins in drool, oils, and residue, rather than just rinsing the surface. Use one sheet of our pet safe laundry detergent for a normal load, two for something heavily soiled or strong-smelling — dropped straight into the drum, not the detergent tray.

4. Add a rinse cycle for set-in smells. If a blanket has been smelly for a while, one wash may only get partway there. A second rinse (or a repeat wash) gives the enzymes a second pass at breaking down what a single cycle missed.

5. Dry it completely. This is the step people skip most often. Any lingering dampness — even the kind you can't feel by touch — gives bacteria exactly what they need to start producing odor again within hours. Run a full dry cycle, or make sure it's bone-dry on the line before folding it away.

When it's not actually the laundry

If a blanket smells strongly again within a day of a proper wash and dry, or if your dog themselves has developed a stronger odor lately, the laundry routine usually isn't the problem — something on their skin or coat might be. The AKC notes that if a dog's odor "seems abnormal or you can't seem to get it to go away," it's worth a check from your veterinarian or groomer rather than reaching for a stronger detergent. No amount of enzyme power fixes a skin or ear issue.

Frequently Asked Questions

Q: Why does my dog's blanket smell bad even after washing it?

A: The odor usually comes back because of leftover moisture, not leftover dirt. Bacteria and yeast on a dog's skin produce odor compounds that only become noticeable when mixed with water — so a blanket that isn't fully dried, or that's used again before it dries, can smell "wet dog" again within hours.

Q: What water temperature actually removes odor, not just masks it?

A: Warm water helps enzyme-based detergents work more effectively than a cold, quick cycle. Cold water is gentler on fabric but does less to break down the proteins and oils behind the smell — if a blanket is machine-safe for warm water, that's the better setting for odor control.

Q: How often should I wash my dog's blanket?

A: Weekly is a reasonable default for a blanket your dog sleeps or lies on regularly, and more often during shedding season or if they've been outside a lot. If it's visibly soiled or smells before then, don't wait for the schedule.

Q: Does this also help with dog hair stuck in the blanket?

A: A little — the static-reducing additive in the sheets helps loosen hair so more of it releases into the lint filter. But for a blanket with heavy embedded hair, pairing it with a pre-wash step like dryer balls gets a cleaner result; see the laundry-and-hair guide linked above.
