Nat, he cant have been losing muscle mass in his head, she posted some pics 2 days prior to the pts, he looked fine!
From what I have read on her FB page, he had calcification in the spine from a bad fall in Oct or last month.
He has always had behaviour probs which when Bev and I went to see him 2 yrs ago, she was on top of and was doing soo well. I know she has had a couple of issues over the last 2 years and was managing him fine but am confused as to which dogs she has at her place and which are at her parents
