Is a spike in appetite normal at around 4 months?

Fargo is all legs right now, and ears, but he seems hungry all the time, literally all the time. He will eat like he is famished every single time, more so than a week or two ago.
He is finally parasite free which is awesome! so its not worms making him hungry.

He is growing super fast right now, he is all legs!

Jennifer, sounds like the puppy hungries Their appetite skyrockets when they start their main growth spurts which I tend to notice is fairly even until about 14-17 weeks and then holy cow its like they grow a foot in a week! 4-7 months lots of growth depending on the breed, then it tapers off a bit to like 9-10 months and then slows again to full growth, age also depending on breed but usually they are done growing upwards by 14-16 months and then they fill out up to 2 years or more.

I noticed pups eating the most in regards to % to bodyweight between 14weeks and 6 months. I'm thinking of larger breed dogs, also, not small breeds.

Loki was hungry from day one, he is a little piggy, but sleek and slim and i cant keep weight on him.
Levi our other husky didnt really care to eat, it just wasn't high on his priority list.
Nico was too long ago to remember!

He is growing so fast, I swear he looks bigger in the morning than he did when we go to bed the night before!

My older mal will eat until she pops and she is a gulper. So I do not gauge the way she eats with overfeeding. Right now she is a bit underweight due to a heat cycle (don't know why but she drops weight while in heat) and constant pacing when outside in her kennel. (she is my problem anorexic child)

Little Em is a pretty normal speed eater and is 20lbs at 17 weeks (ish)
The best thing I found for her was a great deal on cases of game hens. Perfect size for her. When I started them, I would cut the legs and wings off and give them to one of the other dogs and then split the rest in half. One half, and some yogurt is one meal, then she gets something different for her dinner. A snack midday is some THK.

I can see a hint of one rib and some ribs when she is running around. But it is really cold and she is a growing girl so a little extra weight does not bother me at all.

So far she has had deer, buffalo, chicken, game hens and turkey and a little organ meat. All stools normal, shiny soft coat, nice white SHARP teeth and energy levels are great. I had the meat cutter cut me some soup bones into puppy size pieces and I scoop out the middle for now.
I hope to phase out the THK soon and go ALL raw. Thankfully she is a dainty bone chewer. I have lucked out in that category.

No difference in Lear's appetite - starving at 8 weeks, still starving at 19 months.

I never make him work too long for a meal - 5 seconds is all to be exact. At 2 seconds of "look at me" he begins to drool, after 5 seconds there's a serious puddle.

Pup only has to sit and look at me for about 1 second before i set his food down, that is plenty at this age.

I got a moleculeball today and i might switch up his breakfast
and lunch and do the muscle meat and yogurt for breakfast sometimes partially in a kong,
and the moleculeball full of dry for his lunch. I generally am busier around lunch time so that way he can eat and stay busy for a while and tire himself out in the process.
I will be happy to switch totally to raw once he is totally OK'd by the vet to be able to handle any pathogens.

oh, he weighs 25 lbs at 16 and half weeks!!!
up from 20 at 13 weeks...hes gonna be a big boy!
