Can I ask some advice. I have 2 dogs, one aged 7 a Lab/German Shep cross and a 10 year old terrior cross. Last few days they have both started not eating at meal times. I have tried changing their bowls, the kind of food they eat and so on. It's been really hot so I have been walking them first thing in the morning and thing at night to make sure they don't over heat. They seem fine in themselves other than being a little more quiet than usual (which I put down to the heat). They still beg for treats and scoff down any bits of sausage or chicken offered but won't eat their dog food. This morning Merlin my lab cross again wouldn't touch his own food, but later ate 2 sausages and a black pudding from mine. Any ideas?
