We have a female Newfoundland puppy. She’s currently 12 weeks old. She’s such a sweet and smart girl and we all love her. My concern is her size. She’s a very picky eater and I have explained my concerns to my vet as well. The vet did agree that she needed to put on some weight as she was a little boney. But I feel like she is really underweight. She’s 12 weeks and weighs 17 pounds. From my research I would assume she should be around the 25 to 30 pounds by now. Now as I mentioned before she is picky when it comes to food. Which from my understanding newfs can be picky. After many failed attempts of trying to get her to eat her food (3 cups a day) she would only eat a total of maybe 1 cup a day. Vet told me to put a tablespoon of canned puppy food and mix it into her kibble. It worked and she was eating 3 to 3.5 cups a day. But then 2 days after adding the canned food she started getting diarrhea. I assumed it was due to adding the canned food. Called my vet and she prescribed endosorb to help. Well it’s not helping at all. I started a bland diet of boiled chicken and rice today and will be taking her to the vet tomorrow to rule out giardia. With all that being said my main question is how much did your female newfie weigh around 12 weeks of age. According to the puppy charts it’s saying she’s only going to be 46 pounds which I know is way to small for a newfie. She is purebred and AKC registered. I didn’t get to meet or see her parents as a friend of mine got her from a breeder but then her husband was tragically killed in a accident and she in all honesty wasn’t in the mindset to care for a puppy. So we went ahead and bought her. I currently have 3 Golden’s and I’ve never got a dog without doing my background checks on the breeder. But I just fell in love with this little girl and grew up around newfs and love the breed. Any info or suggestions would be greatly appreciated.
