My Golden, Biscuit, shed so much last spring that I started finding fur in my coffee. Not one or two hairs. Actual clumps. I thought something was wrong with him. Turns out, most excessive shedding comes down to a handful of fixable causes, and once you know which one you are dealing with, you can do something about it. This list covers the 10 most common culprits, with practical steps for each.
One thing I will say upfront: the single biggest lever most pet owners are missing is a proper deshedding rake. Not a cheap bristle brush, not a slicker. A rake with teeth that actually reach the undercoat. The Maxpower Planet double-sided grooming rake is what I use on Biscuit twice a week, and the difference it made in the first session was embarrassing, because I had no idea how much loose fur I was leaving behind before.
Your brush is not touching the undercoat. This rake does.
The Maxpower Planet double-sided deshedding rake has over 57,000 reviews and a 4.6-star rating. One side handles thick mats, the other pulls loose undercoat. It costs less than a single grooming appointment.

Dogs and cats shed their undercoat in spring and sometimes again in fall. This is normal, but it can look alarming if you are not prepared for it. A double-sided deshedding rake, used two or three times a week during peak blowout, can remove more loose fur in one session than a standard brush removes in a month. Do not wait for the fur to land on your couch. Get ahead of it.
Irregular Grooming Schedule
When loose fur sits in the coat for days without being removed, it mats, traps dander, and eventually falls out in large clumps. Grooming every two to three days during peak shed season keeps the cycle from getting out of control. The Maxpower rake takes about 10 minutes on a medium-sized dog and pulls out far more fur than any slicker brush I have tried.
Low-Quality Food
Coat health starts in the food bowl. A diet low in omega-3 fatty acids, zinc, or quality protein produces a dull, brittle coat that sheds more than it should. If you recently switched foods and noticed a spike in shedding, the new formula may be the culprit. Look for real meat as the first ingredient and omega-3 content on the label. Better food alone will not eliminate shedding, but it reduces it noticeably within a few weeks.
Dehydration
A dry, flaky coat is one of the first signs of chronic dehydration. Skin cells turn over faster when they are not getting enough moisture, and that means more fur hitting your floor. Make sure fresh water is always available, and if your cat is a reluctant drinker, a circulating fountain can encourage more consistent intake. Hydrated skin sheds less.
Skin Allergies or Irritation
When a pet is itching constantly, the scratching and rubbing loosens far more fur than normal grooming would. Allergies can come from food, pollen, mold, or contact irritants like certain carpet cleaners. If your pet is also scratching, licking paws, or has reddish skin, talk to your vet before assuming the shedding is the main problem. Treating the itch treats the fur loss.
Stress or Anxiety
Stress triggers a physiological response that can accelerate hair loss. A new pet in the house, a move, a schedule change, or even ongoing noise can cause a pet to shed more than usual. You will often see it spike in the days after a vet visit. If the elevated shedding lines up with a stressor, it will usually normalize once the cause is removed. Regular gentle grooming sessions can also help, since many dogs find brushing calming once they are used to it.
Hormonal Changes
Intact female dogs shed heavily during and after heat cycles. Pregnancy and nursing also trigger dramatic coat changes. Hypothyroidism, Cushing's disease, and other hormonal conditions can cause patchy or generalized shedding in both dogs and cats. If the shedding is accompanied by weight changes, skin changes, or shifts in behavior, it is worth a vet visit to rule out an underlying condition.
Wrong Tool for the Coat Type
A slicker brush on a double-coated breed is like sweeping a carpet with a toothbrush. It does something, but not much. Double-coated dogs, which includes Golden Retrievers, Huskies, German Shepherds, Labs, and many mixed breeds, need a rake or undercoat-specific tool that reaches past the outer coat to remove loose fur at the root layer. The Maxpower Planet rake has two sides: 9-tooth for deep detangling on one side and 17-tooth for fine deshedding on the other. That combination handles most coat types without switching tools.
Not Enough Bathing
Bathing loosens dead fur and helps it exit cleanly rather than drifting off the coat in small bits for days. Most double-coated dogs do well with a bath every four to six weeks using a deshedding shampoo, followed by a thorough blow-dry and brushing session while the coat is clean. Bathing too infrequently lets dead fur accumulate. The post-bath brush is where the rake really earns its place: pulling loose fur while the coat is freshly clean and not tangled is the most efficient deshedding you can do.
Parasites
Fleas, mites, and mange cause intense itching that leads to scratching, biting, and pulling fur out. If you see thinning patches, particularly around the base of the tail, belly, or behind the ears, do not assume it is normal shedding. Look for flea dirt (small dark specks) or contact your vet. Parasite-related fur loss requires treatment, not just better grooming tools.
What I'd Skip
I have spent money on deshedding sprays that did not noticeably reduce loose fur. I have tried lint roller subscriptions that are expensive for what they do. I have tried cheap rubber brushes that pull the outer coat without touching the undercoat at all. None of those solved the problem. The tools and habits on this list work because they address the actual cause. The grooming rake matters more than most people expect, but only if it is the right kind. A rake that reaches the undercoat changes your maintenance routine in a way that a $4 bristle brush never will. If you read the full 8-month Maxpower rake review, you will see exactly what consistent use looks like over time. Or if you want the full system, the step-by-step at-home shedding reduction guide walks through the complete weekly routine.
Most pets do not over-shed because of bad genetics. They over-shed because of one or two fixable habits, and the right rake in the right hands fixes more of it than anything else I have tried.
