Once you’ve identified the pattern, use these cause “buckets” to choose the right next step.
If it’s breakage (short pieces, rough ends, thinning at friction zones): Common drivers include over-brushing, brushing dry coat aggressively, heat from high-temperature drying, or harsh/too-frequent shampooing. Action bucket: reduce friction (harness/collar rub), handle the coat gently, avoid high heat, and reassess how often and how forcefully you brush.
If it’s retention (mats, comb won’t reach skin, big bath-day release): The usual issue is insufficient line-brushing frequency for the dog’s coat length and activity level. Clip length matters: longer coats raise mat risk, especially at ears, armpits, collar line, and tail base. Action bucket: increase line-brushing consistency, keep high-friction areas tangle-free, and consider whether the current clip length is realistic to maintain.
If it’s true shedding (full-length hairs from the root, gradual increase): This can be seasonal turnover or stress-related. Action bucket: track changes alongside routine disruptions, diet changes, or recent illness.
Rule-outs and vet triggers: Do a quick parasites check—look for fleas/flea dirt, and contact your vet if you suspect mites. Call the vet promptly for bald patches, inflamed or oozing skin, intense itch, or endocrine red flags like symmetrical thinning, lethargy, and weight change.
