my five month old staffy is teething right now and her teeth are bleeding so shes started to leave her dry mix which is arden grange. she refused it this morning when the wife had softend it  . the this lunch time i gave her half her dry mix with some rice chicken and boiled egg and she ate the lot is this just a teething problem or is she starting to get fussy any idears .

Both.

Because a dog is feeling a little less than 100% in some cases this is when owners start to panic and change foods.

Most dogs like to chew something with a little give in it so think of frozen raggers, stuffed kongs etc which may ease any discomfort and just keep providing the usual food,
