I think you can use anything you want except onion and garlic.
From PetMD (https://www.petmd.com/dog/conditions/toxicity/are-onions-and-garlic-bad-your-dog): "Any member of the Allium family—onions, garlic, leeks, and chives are the most common reported to cause toxicity—contains N-propyl disulfide,” says Dr. Ann Hohenhaus, staff doctor at NYC's Animal Medical Center. “This compound damages the oxygen-carrying substance found in red blood cells called hemoglobin.”
This kind of damage can cause red cells to rupture and be cleared from circulation faster than normal. This condition, hemolysis, results in anemia and red or brown urine. “In severe cases, the anemia may lead to internal organ damage, organ failure, or even death,” says Konecny. If your pet has eaten any garlic or onions he or she may also experience gastrointestinal irritation.
