Hey Everyone, I just signed up to the forum and thought I would introduce my new bullmastiff pup, her name is Loki, she is 8 weeks old. A little bit about Loki, she's 8 weeks old and has her first vet check up and vaccinations in 2 weeks time. I believe she may be underweight, at 8 weeks she only weighs 8.4lbs and she was the pick up the litter, and stands 9 1/2 inches from front toe to shoulder. I seen both of her parents and they where huge bigger than most pictures I have found online typical of the bullmastiff breed, and she was the largest pup out of the litter. I believe her weight issues are down to the food she had been given so I will be transitioning her onto high quality large breed puppy food. I noticed the bullmastiff weight chart thread so will post in there regularly, please let me know if you think she is underweight it would be good to get a second opinion. She seems pretty intelligent, I have taught her the sit command in half a day without the use of treats and seems eager to please. That's all for now folks, let me know what you think.
