Why is my teething puppy not eating as much?

Some puppies eat a little slower or leave a small amount of kibble during the most active teething days, then return to normal appetite within a few days as the discomfort passes.

Adding a small amount of warm water to soften kibble, or offering slightly smaller, more frequent meals, often gets a teething puppy through a sore stretch without a real drop in nutrition.

Watch how your puppy approaches the bowl during a low appetite stretch: eager to start but pulling away after a few bites points toward mouth discomfort, while showing little to no interest from the outset is more likely something else entirely, whether an upset stomach, stress, or a change in food.

Splitting the usual daily amount into three or four smaller meals rather than two larger ones can make each individual sitting feel more manageable for a puppy whose mouth tires quickly, and this is a simple adjustment to try for a few days before assuming a bigger problem is at play.

Track roughly how much your puppy actually eats over two or three days rather than judging by a single skipped meal, since one off day is common and rarely meaningful, but a genuine downward trend across several days is the pattern actually worth acting on. Keeping mealtimes calm and unhurried during this stretch also helps a sore mouthed puppy eat more comfortably.
