We have a lab who is 12 and a half years old. He has arthritis in his back legs, which he is on medication for.
I just got in from work, and he was all over me at the gate as usual, jumping up and down and running around excitedly. He waited patiently as usual while I unlocked door and turned off alarm, again all normal so far.
But then when I gave him the 'you can enter' signal, which usually results in him bounding off like a loon and running all around the house, he just took a step forward and in slow motion his legs collapsed beneath him. Then he slowly rolled onto his side and kind of pawed the air with all four legs, I think that lasted about 10 seconds. He didn't seem to be having any trouble breathing and wasn't making any noise. Then the pawing stopped and he rolled back onto his tummy, and just lay there for a bit very still, and I just stroked him and stroked him. Finally he pulled himself up (a bit stiffly, but that's always the case now) and walked off with me when I encouraged him.
He seemed pretty much normal directly after, wanting to rub up against me and play with his ball etc. He's asleep now (about 1 hour later) but again, that's pretty normal.
Am just worried especially because we are supposed to be dropping him at a friend's house later tonight, who will look after him while we go away to see my parents for four days. This friend is great with dogs, absolutely loves our dog and has looked after him many times before. But now I am just freaking out in case something happens while we are away. On the other hand, this trip has been booked and paid for for ages, we've organised the time off work and part of the reason for going is to see my mother who is also ill herself (though not life threatening or anything). She'll be so disappointed if we don't go, we don't live in the same country so don't see them often.
Does anyone know what this mini-episode thing might have been? And whether it is something that is likely to recur? Obviously we need to take him to the vet, but should we be absolutely delaying our trip to organise that, or can we do it on Monday when we get back? I just don't know enough to know if this is a really sinister sign of something we should be really worried about, or just an old dog getting a bit too excited and falling over because of the existing arthritis.
My poor dog, I felt so scared for him and I can't bear the thought of leaving him, even though he'd be in very good hands with my friend whom he loves. But then telling my parents we can't go, and then him being fine all weekend would be really hard too. Any advice would be really gratefully appreciated.
