My 7 month old puppy has been eating the same food since 8 weeks and now she does not want to eat. I was worried about a blockage from maybe something she should not have eaten, but she will eat table scraps if offered. I tried just letting her skip a meal, but the next meal I have to coax her and then she only eats half what is offered and walks away. Do we need to see a vet or is just a stage?
