My daughter has a big ESS.  He was 32kg, but she has put him on a diet for the last 3 months, giving him 100g of dry food twice a day.  Im a little worried that this is not enough for him. He is now 28kg.

Should be a maximum of 26 kilos so weight going in the right direction. Well done.

Gaby, by BIG I mean Denzil looks more like a show ESS,(they are bigger than the working breed) although his parents are working ESS.  He was the only pup in the litter to turn out huge :-) The only difference in him not looking totally like a show dog is his ears are set too high lol! My daughter is thrilled that he now has a waist :-)

The weight I quoted is for a show ESS. A working type would be even lighter.

hi,
I have smallish working type male. He is fed approx 300g of AG salmon per day. He gets extras too, such as chicken, tuna, veg a few times a week. He is quite lean but not skinny (no sign of ribs any more). If you are trying to get weight of your boy then carry on feeding as you are, but obviously if the weight drastically reduced then you would have to alter the amount/type. I would say if he seems hungry then adjust the amount, but in my expierience he would eat all day if he could! I agree with post about weight of working types, but if hes big then thats what he is. Ive seen working types the size of labradors in the past!
What is he fed at the moment out of interest?

If the adverts are to be believed the amount of food required would vary dependant on the brand being fed. The more expensive foods saying that you need to feed less of their product. It would be interesting to hear if other owners can agree or not with this statement. My opinion is that like us owners, each dog is an individual and you must see for yourself, by the condition of your dog. You should be able to feel but not see the ribs and this should be your gauge. My 2 are terrible scavengers and anyone would think that they are starved, the way they graze the local park but to be honest, both could do with losing a few pounds (me too)

agree with what you say gabby,
I tried my boy on Autarky and was having to give him nearly double what i do AG. Switched back as it gave him terrible wind and caused itchyness. Mine doesnt carry weight but like i said you can feel but not see his ribs. Vet was happy with his weight when we last paid a visit. I would probably like him to carry a bit more weight but he just isnt a big built springer, and will always be lean. Hes happy, healthy and always gets compliments when were out so im happy. Id love another, but he needs some more work before introducing another.

Good idea to get one trained before adding another. New pup will copy the existing one so you could end up with double trouble on your hands. I have two but only 1 is a springer the other a golden retriever. Would love to have a 3rd but OH needs convincing. My preference for feeding is raw, and here the guide is between 2-3% of their ideal body weight per day. If they are Chubby like mine feed 2% if skinny feed 3% seems much easier to me than complete when you realy don't know how much to feed unless its by trial and error.

Raw feeding is still trial and error, one of mine puts on weight really easily with raw and one struggles to put on weight with anything so I constantly adjust amounts.  They are back on complete at the moment and again depending on how much exercise they have had depends on the amount I feed them.

Mine are on Burns and they recommend 8 grammes of food per kilo of dog.

This is why I gave the feel guide. Our pets are just like us, no two exactly alike. Charts and guidlines are just that, not to be strictly adhered to. 

Yes, every pet is an individual, both my dogs are fed BARF and one puts weight on quickly the other could eat and eat and stay slim.
I think it is more to do with one being entire (the slim one) and the other castrated (the one inclined to put on witight).  With a raw diet it is easy to control the weight by adding more veg/fruit and reducing the meat (to lose weight) or vice versa to add weight.

I think with pet foods you have to go by the way your dog looks and behaves, if he/she looks slim and is active then that diet is suiting them, but if they are over weight and/or lacking in energy then you need to rethink their diet.
