You can adopt an English Toy Spaniel at a much lower cost than buying one from a breeder. The fees to adopt an English Toy Spaniel range from about $100 to $500, which covers the expenses of caring for the dog before adoption. In contrast, buying English Toy Spaniels from breeders can be prohibitively expensive. Depending on their breeding, they usually cost anywhere from $1,500 to $4,000.
