Whippets Common Health Issues

Whippets are a popular breed of small to medium-sized dogs known for their loving and loyal nature. While they are generally healthy, some health conditions affect the breed more commonly than others.

These include cardiac disease, deafness, pancreatitis, hypothyroidism, and vestibular disease.

1. Cardiac Disease: Heart disease in Whippets refers to an inability of the heart to pump adequate blood to the body. Symptoms may include shortness of breath, fatigue after exercise, and coughing or fainting spells due to reduced oxygen flow throughout the body. 

Treatment typically involves medications such as diuretics, and ACE inhibitors and lifestyle changes like weight management and regular exercise.

2. Deafness: Usually caused by a lack of pigment development within their inner ear canal, making them unable to hear certain sounds or frequencies properly, resulting in hearing loss on one or both sides depending on severity levels.

3. Pancreatitis: An pancreas inflammation usually caused by various factors such as diet, medications, or underlying medical conditions. Symptoms may include vomiting, diarrhea, pain, and decreased appetite. 

Treatment typically involves fluids, antibiotics to prevent secondary bacterial infections, pancreatic enzymes, and other medications from reducing inflammation.

4. Hypothyroidism: Caused by an underactive thyroid gland, resulting in lower levels of hormones that help regulate metabolism and organ functions. Symptoms may include weight gain, hair loss, skin discoloration, lethargy, and decreased appetite. 

Treatment typically involves daily medication to replace the lack of hormones within the system.

5. Vestibular Disease: Affects the balance and coordination system in dogs, particularly affecting Whippets. Symptoms may include head tilting, loss of balance, and circling behavior. 

Treatment typically involves antibiotics to help treat underlying infections and medications to reduce inflammation and improve coordination.

Tips for Maintaining Good Health in Older Dogs

Here are a few simple tips owners can follow to help their senior canine companions stay healthy. 

1. Exercise: Regular exercise is essential for older dogs to help keep their muscles and joints strong. Even light activities such as walks or playing fetch can benefit aging dogs.

2. Nutrition: Ensure your pup receives a diet of essential vitamins and minerals appropriate for their age. Consider switching to an older dog food formula.

3. Schedule Regular Vet Visits: It’s essential to take your pup to the vet regularly in their later years to help detect any age-related issues or illnesses early on and ensure they receive necessary treatments.

4. Mental Stimulation: Keeping your aging pup mentally active is just as important as physical exercise. Interactive toys and puzzle games can help keep their mind sharp and prevent cognitive decline.
