Our team of creative engineers has over 3 decades of experience in the building and installation of custom caging, enclosures, housing, and research tools. From large-scale big cat enclosures, to mobile animal research crating, Otto Environmental has done it.

The Z-Toy heavy duty enrichment devide collection from Otto Environmental—featuring the Z2, Zyro, Zigg, and Zoy—offers a range of durable, non-toxic enrichment devices designed specifically for large dog breeds and service animals. Each toy is crafted to withstand the most aggressive chewers, from breeds such as Greman Shephards, and Belgian Malinois. These enrichment devices not only provide oral stimulation and mental engagement but are also ideal for training service dogs in fields such as search-and-rescue, police work, and therapy. With a focus on toughness and versatility, the Z-Toys are built to handle intense play, from chewing and licking to tug-of-war, while maintaining hygiene and safety standards for professional and everyday use.
