I just got back from the vet with Madeline.
Over the last 3 weeks she's been having trouble getting up and down and was yelping when she came inside (it's a small step up).
I thought it was her foot that was hurting since she got it caught in the door the night before this started but I've now noticed she struggles to stand when she wakes in the morning and when she's been asleep during the day.
The vet say it's the onset of hip problems (maybe hip dysplaysia but untill we get xrays wont know for sure)
Her back legs dont extend nearly as well as they should for a dog her age (she's 4)
She's getting injections for the next 4 weeks and is on anti inflamatorys to see if that helps but it doesn't look great.
We have to limit her running around now, no ruff playing (thats going to be interesting) and increase her mental training to work off the excess energy.
I'm so up set, this is the last thing I thought would happen to her
