We are having a lot of trouble organising how much we should be feeding Ruby. She is a 12-week old labradoodle and is growing very fast (but no faster than a normal pup, I would think). We thought that perhaps we probably weren't feeding her enough so we started bulking up her meals a bit and have noticed quite a radical change in her behaviour - she is much calmer and more mellow, doesn't nip and bite as much, and seems more contented. However, I have seen and read in quite a few places that we should be feeding her four times a day - and one site said as much as she can eat in 20 minutes! We feed her puppy biscuits and puppy meat three times a day, and a couple of times a week she gets a raw egg and some yoghurt. But the food is literally gone within three or four minutes, which makes me wonder is it enough? She also gets a small bone at night. I have been told by many people that Labrador breeds will eat anything and everything and always look hungry even if they're not, so be careful not to overfeed them. But I can't help feeling like she's not getting enough. Any advice???
