FAQ
Q: What is the single most important thing I can do to protect my dog's health?
A:Establish and maintain a relationship with a trusted veterinarian and commit to annual (or bi-annual for seniors) wellness exams. These check-ups are the foundation of preventive care, allowing for early detection of issues, timely vaccinations, and personalized advice.
Q: Are "natural" or homemade diets better for preventing diseases like obesity and allergies?
A:Not necessarily. While well-intentioned, homemade diets are incredibly difficult to balance correctly and can lead to severe nutritional deficiencies or excesses. For dietary management of health issues, consult your veterinarian or a board-certified veterinary nutritionist. They can recommend or formulate a diet that is complete, balanced, and tailored to your dog's specific needs.
Q: My dog seems fine. Is heartworm prevention really necessary every month?
A: Yes, absolutely.Heartworm disease is transmitted by mosquitoes and is costly, difficult, and risky to treat. Prevention is safe, effective, and far more affordable. Given that mosquitoes can appear in colder months and indoors, year-round, monthly prevention is the standard of care recommended by all major veterinary associations.
Q: How can I tell if my dog is in pain from something like arthritis?
A:Dogs are experts at hiding pain. Watch for subtle behavioral changes: reluctance to jump, climb stairs, or go for walks; stiffness when rising; lagging behind on walks; decreased interaction; or even increased irritability. Never assume slowing down is "just old age"—consult your vet for a proper assessment and pain management plan.
Q: Are certain dog breeds more prone to specific diseases?
A:Yes, genetics play a significant role. For example, large breeds like German Shepherds are prone to hip dysplasia, while Cavalier King Charles Spaniels have a high incidence of heart valve disease. Knowing your dog's breed-specific risks allows you and your vet to implement targeted screening and preventive strategies early in their life.
