No, not to put in water, just to give by mouth. I bought some chewables today, and am wondering if they are safe. I am concerned about Buddy, there doesn't seem anything very obvious like water eyes or coughing, just lethargic. He has been to the vet, and she is treating him with Zythromax for 10 days. I am wondering if, despite the veggies twice a day, if he has a deficiency. He gets red leaf lettuce, cilantro, green bell peppers every day. Endive when I can find it, and carrots and apples for treats. Any words of advice?
