Hello, sorry to hear about Lucky. This may or may not be related to his giardia treatment at all. You can try to offer different forms of food, including plain white rice, skinless and boneless boiled chicken, and low fat cottage cheese. If he is not eating like his normal self in 2-3 days, is acting lethargic, has vomiting, or recurrent diarrhea then Lucky is gonna need to be re-evaluated by his veterinarian. Re-infection with giardia is always a possibility, but there are also other causes for a decreased appetite such as dietary indiscretion, ingestion of foreign material, liver or kidney disease. Please have Lucky evaluated is he is not better in 2-3 days. Hope this helps and best of luck.
