Yes, Spot and Tango is a legitimate company. They offer dog food products that are highly rated by customers and experts alike. The company is known for its transparency about the sourcing of their ingredients, which come from local farms and human food suppliers in the United States. They also provide information about their environmentally-friendly packaging and how the products are made. However, it's worth noting that Spot and Tango's products can be more expensive compared to other brands, with prices over $50 per week for a 30-pound dog. They currently offer three recipes, one of which is grain inclusive. As with any pet food brand, it's recommended to consult with a vet to ensure it meets your pet's specific dietary needs.
