Thats sooooooo good to know!! I called the breeder, to let her know what the vet said, and she told me not to worry. Marley's brother is also "too heavy" for their vet as well... The breeder said that Marley and his brother's bones are big and heavy. They were never the runts of the litter to begin with, so I guess I won't worry too much... but I have cut back on food... I also think he has begun teething, because everything he chews on now, like slippers and his stuffed toys, are like super wet... reminds me of when my human kids were teething!Both my boys averaged about a 10 pound weight gain a month. So at three months, they were already around 30 something pounds.
