Puppy feeding and growth
How does teething affect a puppy's appetite?
Last updated 23 September 2026 · How we write and check this
Short answer
Teething, roughly between 4 and 6 months when adult teeth come in, can make some puppies hesitant to chew hard kibble due to sore gums, leading to slower eating, picking at food, or briefly reduced appetite. This is usually short lived and resolves as each tooth finishes coming through.
Why sore gums change eating behavior
Biting down on firm kibble can be genuinely uncomfortable when a tooth is actively erupting or a baby tooth is loosening, which is enough to make some puppies eat more cautiously or leave food they would normally finish quickly, even though hunger itself has not changed.
Helping a teething puppy eat comfortably
Lightly moistening kibble with warm water for a few days during a particularly uncomfortable stretch can make meals easier without changing the food itself. This is usually only needed intermittently, around the times specific teeth are coming through, rather than for the entire teething period.
When reduced appetite is more than teething
A brief dip in eagerness around known teething stretches is normal, but a puppy that stops eating altogether, seems to be in significant pain, or has swollen or bleeding gums beyond what is typical should be checked by a vet rather than assumed to be ordinary teething.
Key takeaways
- Teething, roughly 4 to 6 months, can cause temporary hesitancy around hard kibble.
- Lightly moistening food during an uncomfortable stretch can help without changing the diet.
- Reduced appetite from teething is usually short lived and resolves as each tooth settles.
- Significant pain, swelling, or a total stop in eating warrants a vet check.
