Sniff it. Most dogs do. A quick whiff alerts them something is ok or not so ok. Similarly, a simple sniff test will suffice if you are checking out plastic pet toys. Toys made from PVC often stink and may have additives like lead, cadmium, or phthalates, a cheap plasticizer that disrupts hormones. Instead, choose pet toys made out of natural fabrics like wool, natural rubber, hemp, or organic cotton. Toys made in USA, like our retro toy collection, are generally a safer bet too.
