7 yo neutered bitch, collie x poodle. Ideal weight is about 11-12kg but recently she's put on weight and is now 15kg (had a very long course of steroids and ballooned!).
The vet used a calculator thing and said she should be getting about 660 calories a day, which is 180g of the kibble I feed. She has a few treats as well; 2 or 3 small biscuits on each walk usually as training treats, plus a piece of dried tripe or similar when I go out and leave her, so I've reduced the amount of kibble and she has two meals of about 75g each. She's walked twice a day; morning for about an hour of ball chasing/running around with her friends, then late afternoon for 30-45 minutes off lead mooching around.
She's not losing any weight and is permanently hungry :( Her stomach is properly rumbling tonight and she's looking at it in disgust!
Any tips? Where am I going wrong?
