Pebble has given you fantastic advice - it's good to have people like this on hand who have lots of experience.
We gave Harley Critical Care syringed, Fibreplex and Dioralyte as he had severe diarrhoea for days. He would only eat tiny bits of fresh grass too but
anything was better than nothing. Metacam was a great analgesia, we increased his dose as he was screaming with pain 8...upon the advice of experienced members on this forum and I spoke to my vet the next morning who agreed.
When I look at the chubby little guy now, it's hard to imagine he had lost that much weight and was giving up, he couldn't hold his head up - truly destroyed me to see my boy like that (still get upset thinking about it

) To see his first 'normal' poo in weeks, had me and OH in tears

as we knew we were winning the fight to save him.
Am thinking of you and your little girl, these stones are a real pain in the ass pow-pow
Hope the little sweetie is up and about really soon, sending more gentle hugs x>>
