Changes in Taste or Smell: Your dog's sense of smell and taste can change over time, and your feet may no longer offer the same appeal as they once did. The smell or taste of your feet may have changed due to changes in your diet, grooming routine, or use of certain products.
Negative Experience: If you have accidentally kicked or stepped on your dog while they were licking your feet, they may associate this behaviour with potential discomfort and have stopped licking your feet to avoid such experiences.
Health Issues: Sometimes, a dog's behaviour changes can indicate an underlying health issue. If your dog suddenly loses interest in activities they previously enjoyed, including licking your feet, it's advisable to take them to a veterinarian for a checkup to rule out any medical problems.
Change in Routine or Attention: If your routine has changed, such as going out more often, working longer hours, or having less time for your dog, they may feel neglected and resort to other behaviours, such as licking themselves or objects, instead of seeking attention by licking your feet.
Competition for Attention: If you have introduced new pets into the household or if there have been changes in the family dynamic, your dog may feel stressed or anxious and redirect their behaviour to compete for your attention. This can result in them shifting focus from licking your feet to other attention-seeking behaviours.
Loss of Interest: Just as our interests can change over time, your dog's preferences and interests may evolve as well. They might simply have found new things or activities that are more engaging and rewarding for them, leading them to lose interest in licking your feet.
Remember that every dog is different, and the reasons for their behaviour changes can be complex. If you're concerned about your dog's behaviour, it's best to consult with a veterinarian or a qualified animal behaviourist for personalized guidance and advice.
