I was just reading around on the site at different topics and decided to search for growth spurts. my pup is starting her 20 week, and was curious to if this is a usually growth spurt time for GSD's. My vet, while getting her 4th parvo vaccine and her last shots till she's a year said that she seemed a little short for her age. I researched height by age, and found the home made chart and for the dogs that had particpated, at the time for her age she seemed right on track. I do know that raw feeding seems to regulate and slow growth a little bit, so maybe thats why the vet thought that she should be bigger? She knew that I raw feed though. anywho, I was just seeing if, and when they hit a growth spurt.
