Alfie is 4 yrs old, is always a bit of a grouch, but seems fit and well.
Over the last few weeks, and in particular the last few days, he has been getting more and more agressive, snarling and snapping at my daughter just for walking within 1ft of him (she is 7yrs and VERY gently and loving towards him), he has been snarling at me and OH and even started guarding his food which he hasnt done before.
Poor Purdey is getting the worst of it, though - he lunges at her, snarling and snapping, everytime she is playing near her - all talk and no teeth, but she is getting really jumpy because of it.
He just seems different in himself - his eyes seem sunken, and he looks worried, if that makes sense. He almost seems depressed! Everything else seems to be working normally - toiletting, walking fine, etc.
Im planning on taking him to the vet tomorrow to see what they say. Any ideas of things I should be asking them to check for? I was thinking of asking for full bloods - Im half wondering if it might be thyroid-related, as he is still overweight despite the diet!
Any advice or suggestions would be gratefully received.
