Decreased appetite

Hi! Pepper is now 15 weeks & in our home 4 weeks. He used to eat 1/4 cup of Eukanuba four times a day, however, he seems to have little appetite the last 3 days. He is his normal active self, but his food intake is about 1/4 cup two times a day. Is this normal?

• My puppy Bubble had the same problem when he was Pepper's age. The advise that I got was to either soften his food with warm water or to add a little boiled chicken's breast /smelly wet dog food to increase the flavour. I guess Pepper must be feeling uncomfortable due to teething problems. Both of the above methods works for Bubble. I hope that it's the same for Pepper too.
