We have just got back from a week away and had friends look after our dog in their home. He seemed fine when we left him and we called and texted during the week to see how is was. All was well and he settled down fine with them.
We picked him up yesterday and he was very pleased to see us all, however he does seem out of sorts. He is very quite and just not himself. He seems to be sleeping a lot and not really eating.
Is this just a phase from a different routine or should i be worried?
