sorry for your loss .........
we are at that point again , Just put our Female Shep down 2 years ago with hip dysplasia and now our male is experiencing the same issues , he is on 300 Milligrams of Gabapentin 3x a day and its to the point of almost no difference when on the med or off the med , definitely in pain but its so hard to make the call to put him down because even though you can see the pain you can also still see some joy when you say his name or pet him he is excited for the attention always .....
then the selfishness we feel is another thing too , are we being selfish , yet on the other hand we call them family members , would I have my wife put down if he hips were going bad ... not hardly ....
such a tough choice
