For enhancing a yard's appearance while ensuring it's safe for dogs, consider plants known for their non-toxicity to canines. Safe options include sunflowers, rosemary, and snapdragons, which add vibrant color and variety. Creeping thyme and buffalo grass are excellent for ground cover, providing a lush, durable surface for dogs to play on. These plants are not only aesthetically pleasing but also hardy and low maintenance, making them ideal for a dog-friendly landscape.
