We are told that once a dog reaches the age of seven it becomes a senior. This may be quantification of age and useful in scientific study, however, we have personally found that the physical state of the dog has a great impact on how true this assessment is. Often our dogs are in good physical health until the age of ten, after that landmark appears to be when we begin to see signs of true aging. We do recognize that at age seven cognition of the risk of aging should be understood, as this is what leads to maintaining optimal physical status. Prevention is the best medicine, as they say.
Caring for senior giant breed dogs necessitates a comprehensive and multifaceted approach that prioritizes their health, comfort, and overall well-being, ensuring they can enjoy their golden years to the fullest. One of the foundational elements of this care is the implementation of a nutrient-dense diet tailored specifically to their needs. It is crucial to provide high-quality protein sources, such as chicken, fish, or lamb, which are essential for maintaining muscle mass and strength as they age. This protein should be complemented with essential vitamins and minerals that support their overall health. As noted, "In other species, digestion and absorption of nutrients can be impaired with aging" (Freeman) leading to an importance to be aware of nutritional needs. The addition of probiotics such as Acidophilus may assist in supporting an aging gut, ensuring that nutrients are still properly absorbed. Discussions with your veterinarian on your pet's changing dietary needs will help frame any additions or changes that will benefit your dog; whether you feed raw, fresh prepared, or kibble, your veterinarian is the best person to discuss any information you are considering and any questions you may have.

In addition to a balanced diet, incorporating joint support supplements is vital for senior giant breeds. Glucosamine and chondroitin are commonly recommended to promote joint health and mobility, while omega-3 fatty acids play a crucial role in reducing inflammation and supporting heart health. These supplements can significantly enhance their quality of life, allowing them to move more freely and comfortably. Sources such as Cosequin joint tablets, and products containing green-lipped muscles help protect joint cartilage. Furthermore, adding antioxidant-rich fruits, such as blueberries, cranberries, and sweet potatoes, can help bolster their immune system, providing them with the necessary defence against age-related diseases and conditions. Vitamin additions such as vitamin B12, D, E and C are easy to add and will do no harm to the system if your pet eats too much; excess is just flushed from the system in urine. There is a great initial study of the effects of dietary supplementation and osteoarthritis here from Elena Amato at the Department of Veterinary Medicine and Animal Productions, University of Napoli.
When it comes to exercise, it is important to choose low-impact activities that minimize stress on their joints while still keeping them engaged and active. Gentle walks in a serene environment or swimming in a safe, controlled, setting can be excellent choices, allowing them to enjoy physical activity without overexertion. It is advisable to establish a consistent daily routine that includes moderate exercise, aiming for around 30 minutes each day minimum. This routine should be flexible and adjusted according to your dog's stamina and energy levels, ensuring that they are neither overworked nor under-stimulated. Remember, older dogs are still the same on the inside as when their body was younger, so they still want to do as much as they did before. Mental stimulation is equally important in maintaining cognitive function as dogs age. Engaging them with puzzle toys, interactive games, or training sessions can help keep their minds sharp and prevent cognitive decline. Incorporation of mind games such as tricky-treat balls, snuffle mats, and kongs with various fillings can help to keep them occupied without stressing their bodies. Activities that challenge their problem-solving skills or encourage them to learn new tricks can be both fun and beneficial, ensuring that they remain mentally active and engaged.
Regular veterinary check-ups are essential for monitoring the health of senior giant breed dogs. These visits allow for the assessment of weight management, joint health, and the early detection of any age-related conditions such as arthritis or heart disease. Your veterinarian can provide tailored recommendations and adjustments to your dog's diet and exercise plan based on their specific health status. Awareness of weight as your dog matures is important to ensure their joints and musculature can handle the coming changes. In the Great Pyrenees in particular, it is imperative to recall that these dogs are NOT meant to be heavy.
According to the CKC standard, males should typically weigh 100 lbs, while females should weigh around 85 lbs. A male weighing about 120 lbs should have a minimum height of 32" at the shoulder. Ideally, no male should weigh more than this. Therefore, if your male exceeds 120 lbs and is shorter than this height, he is likely overweight. It's crucial to remember that these dogs are bred for high altitudes and extensive walking, so being too heavy would hinder their intended purpose. We frequently see owners trying to flaunt their dog's weight as if it reflects the dog's worth; however, you should appreciate your dog regardless of how impressive it appears to others. In this situation, human vanity might lead to an early demise for their pet.
Creating a comfortable and supportive living environment is another critical aspect of care for senior giant breeds. Orthopedic beds designed to provide joint support can significantly enhance their comfort, especially for dogs suffering from arthritis or other joint issues. Heated sleeping pads, or magnetic bedding can aid in keeping joints comfortable, ensuring appropriate blood flow and decreasing inflammation. Additionally, the use of steps or ramps can facilitate easier access to cars, furniture, or other areas of the home, reducing the strain on their joints and promoting independence. Pyrenees being as stubborn as they are, it is often important to create gradual transitions to their usual raised surfaces - if it is too obviously for them, they will not use it!
In conclusion, caring for senior giant breed dogs requires a comprehensive approach that includes a balanced diet, suitable exercise, consistent veterinary care, a comfortable living environment, and mental engagement. By thoughtfully addressing each of these aspects, you can help ensure that your cherished companion not only has a longer lifespan but also maintains a high quality of life in their senior years.
