I know there are some people on here who really understand dog's behaviour so looking for some advice.
Our two year old working cocker spaniel was in the garden for ages on Thursday and when I called him in her dropped a dead baby bird which was upsetting. We disposed of it in the bin. Obviously we don't know if he found it dead, or whether it was alive and he killed it, we have no way of knowing. Anyway ever since this happened , he keeps going back to the spot where he was when I called him in and lying there looking mournful and moping around, won't come in when called etc. Is it just that the bird has disappeared and he's looking for it ??
