Separation anxiety isn’t just a dog thing. Dogs, cats, and even horses can develop unhealthy attachment patterns that show up as distress the moment you’re out of sight. If these are left unaddressed, it can escalate into destructive behavior, self-injury, or attempts to escape. Here’s what it looks like in each species, and 18 practical ways to help.

Pet Separation Anxiety 101

Separation anxiety begins with distress in the absence of whoever (or whatever) the pet is overly attached to. That excessive dependence, whether it’s on a person or another animal, isn’t healthy and needs to be addressed for the pet’s overall wellbeing. If ignored, it can escalate into behavioral and destructive issues, self-injury, or even escape attempts.

Separation Anxiety in Dogs

Common symptoms of separation anxiety in dogs include:

  • Barking, howling, and whining
  • House accidents, including coprophagia (eating stool)
  • Chewing, digging, and other destructive behaviors
  • Escape attempts
  • Pacing
  • Drooling, panting, or excessive salivation

Why it happens: abandonment, a change of schedule, home, or guardian, sudden loss of a family member, or an underlying medical issue.

What helps:

  • Desensitization. Leave for a few minutes, then return. Gradually increase how long you’re gone.
  • Build a departure routine. Ask your dog to sit, offer a high-value treat, then leave calmly. Fold this into the desensitization process above.
  • Exercise before you leave. A tired dog is a calmer dog.
  • Consider a second dog, if your household can support one.
  • Keep arrivals and departures low-key. No big buildup either direction.
  • Leave a filled, frozen Kong to keep them occupied.
  • Talk to your vet about homeopathic or pharmaceutical options if the behavior is severe.

A dog working through separation anxiety often self-soothes in ways that show up in their coat, more shedding from stress, more matting from pacing and scratching at doors. Regular brushing with the EquiGroomer for dogs is a low-key way to build in calm, hands-on time as part of that departure or return routine.

Separation Anxiety in Cats

Separation anxiety shows up in cats more than most owners expect. One study found 64% of cats evaluated showed measurably less stress when with their caregiver, evidence this isn’t just a dog phenomenon.

Common symptoms include:

  • Crying or yowling
  • Accidents outside the litter box
  • Destructive behavior (more common in male cats)
  • Excessive grooming (more common in female cats)
  • Hyper-attachment to their caregiver

Why it happens: being female, living exclusively indoors, or having been weaned too early, bottle-raised, or orphaned.

What helps:

  • Reward calm, not clinginess. Give attention when your cat is lying down, sighing, or has a loose tail and closed eyes. Ignore attention-seeking behavior.
  • Tire them out before you leave with a play session.
  • Keep them occupied while you’re gone: cat-safe TV, puzzle feeders, or treats hidden around the house.
  • Stick to a consistent routine.
  • Consider a second cat, if your household can support one.
  • Talk to your vet about homeopathic or pharmaceutical options if needed.

Since excessive grooming is one of the more common stress responses in cats, it’s worth keeping an eye on your cat’s coat condition during a stressful stretch. The EquiGroomer helps manage the overgrooming fallout, thinning patches, hairballs, without adding more stress to an already anxious cat.

Separation Anxiety in Horses

Horses are herd animals, and that instinct doesn’t switch off just because they’re stabled. According to Dr. Camie Heleski, an equine behavior and welfare researcher at the University of Kentucky, horses are wired to seek safety in numbers, which is exactly why isolation, even briefly, can trigger real distress.

Signs of separation anxiety in horses include:

  • Frequent, abnormal vocalizations
  • Shaking or trembling
  • Increased heart rate and sweating
  • Loss of appetite or refusal to drink
  • Rearing, kicking out, bucking, spooking, pawing, or bolting
  • Pacing or fence walking

Why it happens: separation from the herd, isolation even for short periods, or particularly strong bonds between specific horses.

What helps:

  • Desensitization. In short training sessions, work on keeping your horse’s focus on you while slowly increasing distance from their companions. Reinforce good behavior with high-value treats or a grooming session at the end to build confidence.
  • Keep separated horses in visual range of each other when full separation isn’t possible.
  • Pair anxious horses with a smaller companion animal, like a pony, goat, or donkey.
  • Keep horses in groups of three when possible, so no single horse is ever left completely alone.
  • Talk to your vet about homeopathic or pharmaceutical options if the anxiety is severe.

A grooming session at the end of a training set does double duty here: it rewards the desensitization work and gives you a read on how your horse is holding stress physically. The EquiGroomer for horses removes loose hair and dander gently enough to use as that calming, confidence-building close, without adding any discomfort to a horse that’s already working through anxiety.

If your efforts to ease your pet’s separation anxiety aren’t working, it’s worth bringing in a certified animal or veterinary behaviorist. This is a real, treatable condition, but it shouldn’t be ignored.
