Hi there everyone, I'm new to this forum so looking forward to some help. Have a 9 month old Bullmastiff pup, my first of this breed. he weighs in at 39kgs and I reckon he's okay, if not a little leggy, here's the thing, I keep getting told by non mastiff owners he needs more weight, are they right? He's currently on an arden grange large breed puppy, and Green tripe mix, with the odd scrambled egg or fresh yoghurt treat with steamed veg too. Any help would be appreciated!! Thanks
