Ok, so I have now decided on 2 meals a day

first meal is 50g of Orijen and their second meal I have been giving them 1/3 tray of Wainwrights

However, I am now startled that Wainwrights state for a small dog (5-12kg) the feeding amount should be 1/4 - 1/3 of a tray PER DAY!

Surely this is not enough? I'd literally be giving them a spoonful for each meal

My dogs are certainly not overweight, but before i was giving them Orijen on a mornign followed by a 150g of JWB each on an evening, is this too much?

They are regularly exercised

My two GRs  have wainwright trays..they have one tray between them with complete at eve meal and just complete for brekkie.
If I was to feed it alone I would give them one tray each for eve meal.
I would just judge it for your self as you know your own dogs best and how much they will eat not to be hungry.

Ive got a cocker spaniel feed once a day and he has about 1/4 of a tray daily with a handful of science plan weighs 15.7KG and apart from the odd biscuit and dental stick thats about all.

Our Border has 1/4 plus 3/4 a bowl of Beta lamp & Rice pluy dental stick and odd biscuits (two on their pillows at bedtime!) he's over 23KG now due a weigh in shortly.

They dont need stuffing and they are doing well on Wainwrights no scurf and silky shiney coats.

I feed wainwrights trays solely to my BC bitch.  She is fed one tray a day but due to her now competing in agility regularly I am going to be upping it as she is losing weight on it and is lean enough already but over the winter when she isnt competing it will be dropped back down on it. 

I am really pleased with the results and the poos are like I was getting from her when she was fed raw so bonus
