Why is my dog losing weight despite normal appetite and activity?

Updated On September 23rd, 2025

Pet's info: Dog | Beagle | Male | unneutered | 5 years and 9 months old | 35 lbs

Dog lost 2kgs in 2 months but is acting normal and his appetite is still huge. Dog has his blood test done and vet said there was no problem. I have been giving him the same amount of food and his activity levels are normal. Are there any other possible reasons for this? Any vitamins/nutrients that he lacks? There were a few high and low levels but vet didn’t mention anything. I attached his bloodwork in the pictures. Thank you.

Thank you for submitting your question regarding Summer. I agree with your veterinarian that the blood panel is unremarkable. However, it is a very small one. A larger more comprehensive panel would be indicated if he continues to lose weight. I would also recommend fecal and urine testing. Be sure to weigh him again on the same scale within the next few weeks to monitor for any further weight loss. I hope this information helps!
