growing

This is my Puppy Graham, I've had him since 8 weeks and he is 13 weeks old today. Last week he had a vet appointment and he weighed a little under 20 pounds. I asked the vet and they said his weight was alright. I've been feeding him Purina Pro Plan for large breed puppies. Two cups a day split...

Just wondering, do puppies hit a growth spurt around 6 months again. I feel from 4 months to now (5 months) she hasn't grown at all. She has started getting more feathers on her tail and chest but overall size hasn't changed. Wanted to see if we should expect her to hit another growth spurt...
