He's been slowing down and doesn't chose to do the stairs anymore.
He's always had a lobsided walk due to his length. He would stiffen up after a walk and sometimes struggle to get in and out of the car but recover after a day or so. His legs have never given way like they did today.
He isn't on any meds and has been taking "joint aid for dogs" for only a month.
He has a sensitive stomach generally but there has been no vomiting or diarrhea.
He weighs approx 38 - 40 kilos but isn't fat just a v large dog.
His only pre exisiting conditions is joint stiffness. He has lost muscle bulk and has become quite bony round his back end.
He has a good appetite and has not cried out in pain but he is a very gentle natured dog.
He did go swimming during this walk which is quite normal for him and the terrain on the banks of the river is uneven which may have jolted his back. This walk was also a bit longer than he has had for a while so I recognise that he may have over done it.
He will stand and walk in the house short distances now we have dried him but his back is quite arched and he is limping more on his right leg
