Jack Russell Terrier Health Issues Associated With Old Age 

As Jack Russell terriers grow old, they become prone to certain health conditions, eventually leading to their death. Some of the health problems that your old Jack Russell terrier might suffer are:

  • Deafness: Like the 21-year-old Boycie from Britain, Jack Russell terriers tend to suffer from deafness during their old age. Typically, deafness can be a partial or complete hearing loss. 
  • Blindness: In most cases, an old Jack Russell terrier will suffer eye problems and sight loss even without typical eye infections 
  • Diabetes: Old Jack Russell terriers are more prone to diabetes due to the lower insulin level in the blood. Some signs of diabetes include loss of appetite, weight loss, and general inactivity.
  • Dental problems: In most cases, Jack Russell terriers will have bleeding gums or decayed teeth in their old age. Some signs of dental problems might include rotten teeth, bad breath, lousy smell, or broken teeth.
  • Weight problems: Since Jack Russell terriers are hyperactive, they play and exercise a lot. Usually, these exercises help burn calories. When they grow old and become less active, they don’t engage in intense exercise leading to obesity.

Tips to Improve the Lifespan of a Jack Russell Terrier 

Even if your Jack Russell terrier is senior and advancing in age, the following fitness and nutritional tips can help prolong the lifespan past the average 16 years mark.

Engage It in Physical Activities 

Lack of enough exercise is the primary cause of obesity issues in old Jack Russell terriers. Consequently, obesity makes the dog prone to health issues such as breathing problems, heart disease, and diabetes. 

Keep in mind that the old dog might not be able to engage in rigorous exercise due to the fragile bone structure and other underlying health conditions such as blindness. However, you can consider engaging it in physical activities that can help burn calories to maintain a healthy weight.

For instance, you can provide it with challenges that can allow it to use its mental energy, such as puzzle-solving games like Outward Hound or engaging it in scavenger hunts. 

Feed It With Nutritious Foods 

Older dogs are more prone to diet-related health conditions such as obesity and diabetes. The best way to avoid these issues is to feed your old dog the right amount of low-calorie foods. 

Ensure the food contains high vitamin and mineral content as they help boost the old dog’s immune system, making it more resilient to diseases.
