how is his hair, is it very thin, if so I would definitely have blood work done on him, a puppy that eats a lot and does not gain weight and has very thin hair could have liver shunt. Hopefully I am wrong, but my friend had a morkie and what made her get him checked out was no weight gain and very thin hair. The only way to tell is through blood work and that would indicate if further testing is needed. I hope it's something else but if it is liver shunt there is a highly successful surgery that can be done.

Before further testing you might want to hurry up and get pet insurance just incase, this way it will not be considered a pre existing condition. If you get insurance make sure you say nothing or that your vet records indicate a future possible condition. I found this out the hard way. Two years ago I mentioned to my vet that Lola panted hard when playing, then when some blood work indicated she could have a muscle strain I decided to get a heart ultra sound, Insurance denied the test because "they claimed" she had a pre existing condition" based on my panting hard comment that were in the vet notes. Meanwhile the heart test was fine. I learned a lesson how pet insurers find it very easy to claim pre existing conditions so they can get out of a claim
