🐕💅 Trimmed nails, happy tails!

Keeping your dog’s nails trimmed isn’t just about looks—it’s about their health and comfort! Long nails can lead to pain, posture problems, and even injuries. So trim every 3-4 weeks to keep them happy and healthy!

🦷 Don’t overlook your pet’s smile! 🐾

At Animal Hospital of Walnut, we know dental care is just as vital for pets as it is for people. Without proper oral hygiene, most cats and dogs develop periodontal disease by age three. Our expert team provides thorough dental exams and cleanings to keep your furry friend healthy, happy, and pain-free. Let’s protect those pearly whites together! 💙
