Selecting the right walking pet toy requires a balance between safety, durability, and interactive features. Buyers should prioritize toys made from non-toxic, BPA-free ABS plastics or reinforced plush fabrics to ensure they withstand pet biting and scratching. For electronic models, verify the motor noise level; high-quality toys use silent motors to avoid scaring sensitive pets. Additionally, look for rechargeable lithium batteries (USB-C) over disposable ones to increase the product's economic value and eco-friendliness.
