So this is my first GSD puppy, and granted she's been a little under the weather of late because of changing her food up ( the other stuff was too rich) and now a possible UTI or something similar. I took her to the vet and weighed her and she weighs 22 LBS, she's 12 weeks old tomorrow, and she just looks skinny! I know she is probably at about 21 LBS right now from being a bit sick ( but still playful) but even before all this to me she just looked skinny, maybe because I was used to me heeler who as a puppy was a bit of a chunk, but the GSD has a very defined waist, ribby/bony. The vet keeps telling me she looks fine, and so does the breeder ( who is a friend). I feel like a terrible puppy mom! Can anyone share their pics of their pups? thoughts? stories?
