How to tell if a Schnauzer is calcium deficient?

To tell if a Schnauzer lacks calcium, observe its body and behavior. First, calcium deficiency can cause bone problems such as easy fractures, bent or deformed legs. Second, it can also cause dental issues like loose or brittle teeth, and during teething a double row of teeth is common. Also, deficiency may cause muscle problems such as twitches or stiffness. Finally, it can change behavior, causing anxiety, irritability, or depression. If you see any of these signs, take the Schnauzer to a vet for a blood test to confirm.
