Coming home to chewed furniture is upsetting, but understanding the cause helps you solve it.

Common causes

• Separation anxiety. See separation anxiety signs in dogs
• Boredom and excess energy
• Teething or normal chewing. See why do dogs chew everything and puppy teething timeline
• Fear of noises.
• Lack of training about what is acceptable
• Insufficient exercise
• Attention seeking in some dogs

It is not spite

Dogs do not destroy things to punish you. Scolding after the fact does not help, since dogs do not connect it to the earlier act.

Anxiety or boredom?

Use a camera or recording to watch. Signs of anxiety include panting, drooling, whining, pacing and focusing on doors and windows. Bored dogs may chew a few items and then settle. Anxious dogs often damage exits and may injure themselves.

If anxiety is likely, see how to help a dog with separation anxiety and speak with your vet.

Meet exercise and enrichment needs

1. Exercise before you leave: a walk, sniffing time or play.
2. Offer food puzzles or lick mats.
3. Provide safe chews that suit your dog's size.
4. Rotate toys.
5. Teach a settle cue. See how to teach a dog to settle

Manage the space

Limit access to a safe room or pen, remove valuables and cords and block off tempting areas. Use baby gates and pet-safe barriers. Crates help only if your dog is comfortable in them.

Gradual alone-time training

Start with short absences, rewarding calm behavior. Increase time slowly and keep departures quiet. Avoid long absences before your dog is ready.

Safety first

Destructive chewing can cause blockages or injuries. If your dog swallows non-food items, call your vet. Remove hazards such as socks, toys with loose parts and toxic items. See is xylitol toxic to dogs for one example of a household hazard.

Daily routine

Dogs thrive on predictability. Provide meals, walks and rest at consistent times. Make sure your dog is not left alone for longer than he can handle.

Professional help

Ask your vet and a certified trainer or behaviorist for help with severe cases. See when to see a dog behaviorist.

Common mistakes

• Punishing after the fact.
• Leaving long hours too soon.
• Providing unsafe chews.
• Ignoring anxiety signs.

Troubleshooting

• He chews the door: consider anxiety and consult your vet.
• He shreds pillows: boredom may be a factor.
• He destroys only sometimes: look for triggers like storms.
• He chews furniture at night: offer chews and check comfort.

A simple plan

1. Observe with a camera.
2. Meet exercise needs.
3. Provide safe outlets.
4. Train gradual alone time.

Real-life examples

A young lab chews cushions and improves with exercise and chews. An anxious terrier damages the door and needs a behavior plan. A teething puppy shreds shoes and learns to chew toys. The cause drives the solution.

Staying patient

Progress takes time. Keep sessions positive, protect your home and support your dog.

Making alone time easier

Give your dog a predictable pre-departure routine: a walk, a toilet break and a chew or puzzle. Leave quietly without long goodbyes. Calming background sounds or music may help some dogs, although they do not replace training. Build up time away gradually.

Safe chews and supervision

Choose chews appropriate for your dog's size and chewing style, and supervise when trying something new. Remove items that can splinter or break into large pieces. If you are unsure, ask your vet for recommendations.

When to get professional help

If your dog injures himself, escapes, soils in distress or becomes frantic every time you leave, do not wait. A vet can check for medical issues and discuss options for anxiety, and a qualified behaviorist can build a tailored plan.

The takeaway

Find the cause, meet needs and train gradual alone time.
