Unless there is some reason why not, I have a nearly full large bottle of metacam I can send you. It was for Freddie who was pts in January and it supposedly lasts a year so it is in date pm me your address if you would like it. Being a large bottle it was about £60 so I didn't send it. It's been kept in my scullery within the temperature range.
Metacam did wonders for Freddie, who was 19 when pts, but stopped working towards the end. He then moved onto tablets but my vet told me it was quite usual to chop and change between treatments.
Hope so much he gets better. 9 is very young and I know what it's like to have a once in a lifetime dog *wibbles for Freddie and Laddie*
