I bred small Westie pups. Until they were 8 weeks old I fed them 4 times a day. and they pooed after each meal plus every morning and night = 6, but were tiny poos and not at all smelly. I fed them Eukanuba. My adult dogs were fed once a day at 4pm
Proplan is very good but expensive, depends on your budget and what you want to feed.
However, there is a lot of food snobbery, the best advice I could give you is try a couple, and keep to it, to avoid upset tummies etc. Lamb and rice dry foods are good for pups with sensitive tummies.
With regard to the poos, if you are feeding 4 times a day, then expect at least 4-5 poos a day. The older they get, the less frequently they get fed, and the less they poo...in times of poo-ing, but the amount increases !
Purina is full of shite, which is why dogs fed on it produce so much shite.
Ingredients of the Beta puppy with chicken: Cereals (wholegrain 20%), Meat and animal derivatives (meat 14%, chicken 4%), Vegetable protein extracts, Oils and fats, Derivatives of vegetable origin (dried beet pulp 1.1%), Vegetables (dried chicory root 1.1%), Minerals.
So only 18% 'meat' (I use the term loosely as much of that could be the animal derivatives which can include hair, feathers, skin, hooves etc. as well as the usual eyes, ears and arseholes), the rest of it cereals. So little 'meat', in fact, that the protein content has to be bumped up with vegetable protein.
i reckon Max does about 5 a day! Is ths normal? They are pretty rank too . He also has the smelliest flatulence I have ever known! He is fed on Purina beta puppy food ( dry food). Anyone got any opinions on this? Thanks mN
