6 months ago I got a 2 year old german shepherd dog from a recue centre. He was found roaming the streets, he was very underweight, I was advised to feed him only complete dried food, for the first 3 weeks I couldn't fill him up he just devoured his food, the vet said he was now normal weight, then suddenly he wouldn't eat this food so I tried all different dog foods, no chance, then I tried meat chicken pasta rice and veg, he just has a sniff and walks away, Im sure if I didn't persuade him to eat he wouldn't bother, I have tried leaving it down for 30 minuites and then moving it, he's not bothered, the only time he will eat is when he's out and I do a recall. He then has biscuits, I have had dogs all my life but I don't know how to make this dog eat.can anyone please help me.
