When does excessive dog licking become a cause for concern?

2. Seeking attention
Dogs are quick learners. “If your dog licks you and you respond — by laughing, talking or petting — they understand that licking gets attention,” he says. Over time, this can become reinforced behaviour.

3. Being submissive
In canine social structures, licking can signal respect. “A dog may lick to show submission, indicating that they recognise you as the leader,” Dr Sharma notes.

4. Exploring their environment
Dogs experience the world through taste and smell. “Your skin may taste salty, or you may smell like food. Sometimes, they are simply investigating,” he adds.

When should excessive licking become a concern?

“Excessive licking becomes concerning when it causes physical damage such as bald spots, redness, sores or open wounds,” warns Dr Sharma.

Pet parents should watch for:

• Licking that interferes with eating or sleeping
• Repeated licking focused on one specific area
• Behaviour that continues despite distraction
• Visible skin irritation or injury

“If a dog keeps licking one particular spot, it may indicate underlying pain, allergies or skin infection,” he explains. “In some cases, excessive licking can also be linked to anxiety or stress.”

Dr Sharma advises seeking veterinary care if you notice wounds, hair loss or if your pet cannot stop the behaviour. “Early intervention helps prevent secondary infections and identifies whether the cause is behavioural or medical,” he says.

In most cases, Dr Sharma adds, licking is harmless and part of normal dog communication. “However, like any behaviour, context matters. If the licking is persistent, intense or causing injury, it’s important to consult your veterinarian rather than dismiss it as just a habit.”
