Petmate Indigo Igloo Dog House Review

Who it’s for

The Indigo is built for one owner in particular: someone whose large dog lives or naps outdoors and needs a genuinely insulating, low-maintenance house without wiring up a heater.

• Great fit: a Lab, Shepherd, Golden, Boxer or similar 50–90 lb dog that wants a warm, dry den
• Skip it if: you have a toy breed (too cavernous to hold body heat), a giant breed (size beyond 90 lb), or you specifically need a powered heated house for sub-zero winters

If that’s not quite you, the lighter plastic boxes and heated options in our dog house guide may suit better.

Structural foam vs. cheap plastic

This is where the Indigo separates itself from the $50 plastic boxes. The shell is structural foam — a dense, double-wall molding that traps a layer of air — rather than the thin single-wall polyethylene most budget houses use. That wall does real insulating work: it holds your dog’s body heat in winter and slows the sun’s heat in summer, which a thin plastic shell simply can’t. It’s also rigid and heavy enough that it won’t flex, crack or blow around the yard. Petmate makes it in the USA from roughly 90% recycled material, and the rounded igloo shape is structurally why it lasts: no flat walls for wind to push on, and snow and rain slide off the dome.

Microban & all-weather use

The Indigo’s liner has Microban antimicrobial protection molded in — it doesn’t kill germs on your dog, but it suppresses the bacteria, mold and mildew that make a damp outdoor house smell sour over a season. Combined with the top vent that circulates fresh air and the raised floor that drains moisture away from the bedding, it’s a shelter that stays noticeably cleaner and drier than a sealed plastic box. The rounded shell deflects wind, rain and snow year-round.

Sizing

The Large reviewed here measures about 43.8″ W × 34″ D × 25.8″ H and is rated for dogs 50–90 lb. Igloo sizing has a twist most owners miss: bigger is not better. You want a house just large enough for your dog to stand, turn around and lie down — and no larger, because a cavernous interior is harder for body heat to warm.

• Measure your dog nose-to-tail and floor-to-shoulder, then add a few inches of clearance
• For a 50–90 lb dog the Large is the sweet spot; smaller dogs are better in the Medium
• Giant breeds over 90 lb should size up to a different house — the Large will feel tight

Cleaning & durability

Practically, the Indigo is about as low-fuss as outdoor houses get. There’s no assembly beyond setting the dome on the base, the structural foam wipes down easily, and the Microban liner keeps odor in check between deep cleans. The raised floor lip means rain and slush drain off instead of pooling under the bed. Owners routinely report these lasting many years outdoors with nothing more than an occasional hose-down — the foam doesn’t go brittle and crack the way thin plastic does. The one honest catch: at 25.8″ tall it sits low, so a very tall dog has to duck.

Value: is it worth ~$129?

At around $129 the Indigo costs more than a flimsy plastic box but a fraction of a heated wood lodge — and the money goes exactly where it should: into the insulating structural-foam shell and the Microban liner. For a large dog that needs a warm, dry, low-maintenance house and doesn’t require a powered heater, it’s genuinely hard to beat, which is why it’s been a best-seller for years. If you need true sub-zero heating, pair it with a heated pad (above) or step up to a heated house.
