Frequently Asked Questions
How can I keep my short-coated dog warm indoors without making them overheat?
Use a low-bulk, breathable insulated vest for core warmth and add a thin breathable shell only when needed. Favor materials like polyester outer shells with mesh or flannel linings that trap warmth but allow heat and moisture to escape. Monitor your dog for panting, restlessness or damp fur—those are signs of overheating.
When should I use a vest versus a full-coverage jacket indoors?
Choose a vest when the main issue is a cool floor or slight indoor chill—vests warm the torso without covering limbs and help regulate temperature. A full-coverage jacket is better for very drafty rooms or short trips outside but can be too warm for prolonged indoor wear unless it has breathable lining and venting.
How do I tell if a layer is causing my dog to overheat?
Watch for rapid panting, seeking cooler surfaces, lethargy, or damp fur beneath the garment. Check the skin by feeling under the layer—if it’s damp from sweat or the dog is breathing fast, remove the layer and allow cooling. Proper fit and breathable fabrics reduce the risk, so choose adjustable, venting designs.
