Hi,
Natures menu and Natures diet both have crushed bone in them so it is good for your dog/pups teeth , it is also a complete meal so you do not need to add anything to it like biscuits or mixer.
The amount you feed them is stated on the instructions , but you have to start off feeding them 70% less then recommended so they get used to it
i have a 5 month old bull mastiff pup and have had the same trouble deciding what food to feed her from the start as she is not keen on dry food and she doesnt like canned food such as winalot/butchers/ pal etc , she will not eat that but she love nature diet and nature menu and also it is all good ingrediants in it with now bad additive or cr*ap basically!
i do leave dried biscuits out at lunchtime for her to nibble if she gets hungry!
i wouldnt give raw chicken wings , as chicken bones sometimes splinter in the dogd stomach but just a knuckle bone or something is fine!
You can get ham bones from tesco £1.99 and my pup loves them!..or pigs ear etc!
Hope this helps!!
