About 79% of dogs eat grass at some point in their lives. It is one of the most commonly worried-about behaviors. Grass-eating is deeply rooted in canine ancestry — wild dogs consumed plant matter from prey. Only about 25% of grass-eating dogs vomit afterward, meaning most dogs eat grass without issue.

Dogs have two small anal glands that produce scent-marking fluid. When these become full, impacted, or infected, dogs drag their bottoms to relieve discomfort. It can also be caused by intestinal parasites, skin allergies, or perianal irritation after grooming.

This is a deeply ingrained instinct inherited from wild ancestors who would circle to flatten grass, leaves, or snow before sleeping — creating a comfortable nest and checking for insects. It is completely hardwired, even in dogs who have never seen grass.

Separation anxiety occurs when a dog becomes distressed after being left alone. It stems from hyper-attachment, prior trauma, or sudden routine changes. It affects 14–20% of dogs and is one of the top reasons dogs are surrendered to shelters. Film your dog after you leave to see their true behavior at home.

Resource guarding is a dog's instinct to protect high-value items — food, toys, resting spots, even people. A growl is communication, not aggression. Punishing the growl removes the warning system and creates a dog that reacts without warning. The growl means: “I am uncomfortable, please back off.”

Leash reactivity occurs when a dog reacts explosively to a trigger (other dogs, people, bikes) while on leash. The leash prevents natural responses (approach or retreat), creating frustration or fear that explodes as barking and lunging. In most cases it is communication, not aggression.

Coprophagia affects about 16% of dogs frequently and up to 24% at least once. It is more common in multi-dog households and can be a learned behavior, a nutritional issue, or enzyme-related. Puppies explore the world with their mouths and mother dogs clean up after their pups — it is deeply instinctual.

Kneading (making biscuits) originates from kittenhood — kittens knead their mother's belly to stimulate milk flow. The behavior persists as a self-soothing mechanism. Cats also have scent glands in their paw pads, so kneading marks territory with their scent signature on soft surfaces and beloved humans.

In wild cat colonies, experienced hunters bring prey back to teach younger cats how to hunt. Your cat sees you as family — and a rather helpless hunter who cannot fend for themselves. Bringing you prey is your cat's way of providing for you and teaching survival skills. It is the highest honor in cat culture.

Cats use their paws to investigate objects before committing to full interaction — a survival behavior for testing whether something is alive or safe. Movement also triggers prey drive, so tapping objects off edges creates unpredictable movement to practice pouncing. They have also learned your reaction is immediate and entertaining.

Litter box avoidance is one of the most common cat behavior complaints. It has both medical and behavioral causes. Medical causes must always be ruled out first. A UTI, kidney disease, or diabetes can cause pain associated with the box. In male cats, urinary blockage is a life-threatening emergency requiring immediate veterinary care.

Cats hear frequencies between 48Hz and 85kHz — humans max out at about 20kHz. Your cat may be detecting rodents, insects, or pipes in your walls that are completely inaudible to you. They also detect light and movement imperceptible to human eyes. That blank wall your cat intensely studies may be a very active rodent highway.
