I wish I could, Minty - the big, daft lump's scared of the bloody rain!
it might be HD mate, i used to keep bullmastiffs, and big breeds like these have bad hips.If it was my dog i would get her x rayed, then you know, and the vet may help you with what ever. another thing get some more weight of her, the lighter the better. get her down to just over 80lb. Both my dogs were big feckers but knocked alot of weight of them. proper Working bullmastiffs that were used for work in the 1930-50s were only -100lb tops, more like the Alunt of today, do the above
