My 6-month-old puppy is eating less. Is this normal puppy behavior?

Updated on September 23rd, 2025

Pet's info: Dog | Labradoodle | Male | neutered | 5 months and 20 days old | 63 lbs

My puppy is a 6 months old Labradoodle. He's always had a good appetite and is still on 3 meals a day. In the last week he's only been eating one meal a day and is not interested at his other meal times. His energy is fine and there's no diarrhea or vomiting. Is it just a lull in his growth where he's not hungry? Should I think about changing his diet?

As long as he is on a good quality, large breed puppy food and is otherwise well, normal growth and a healthy, shiny coat I would not change his diet. The more variety he is offered at this age the more likely he is to develop into a picky eater and refuse foods regularly! Most pups will have a reduction in their appetite as their growth slows, or ha may have picked up a mild infection etc. Monitor over the next 5-7days a schedule a vet check if any further symptoms develop

    Yes this is absolutely normal. He is 6 months old now and his caloric intake is decreased by about 1/8-1/4. So a slight decrease in his food intake is no cause for alarm. Best wishes with your puppy. Take care!

    Forcsome reason a lot of puppies go through a phase where tgey lose interest in their food, it does tend to happen between 6 months and a year. It is likely to do with the major debelopment cycles. As long as Fiddle is bright and energetic, and not losing weight I would not worry overly. If you notice weight loss or change in his faeces I would have him checked by the vet in case there is an underlying issue. In the mean time you can either persevere with the same food or try somethibg different. Bear in mind that if you coax him with lots of tasty things he may become a little spoilt. Dog food does tend to be very high in energy so he is likely getting enough. Usually after a month or so they start eating properly again.

    Instead of feeding her twice a day, feed her 4-5 times a day and smaller amounts. You may also want to try another puppy food which may be more palatable to her and might have a higher concentration of nutrients per cup, so that you can feed less than your present feed, but still give her the right amount of nutrition. Since she is 6 months old, and it is spring time, it is also possible that she is preparing for heat and may not be as hungry as usual due to hormonal changes. Sometimes teething also can hurt and make her want to eat less. Check her mouth for sores.
