A feeding tube can be placed very quickly under anesthesia, either through the esophagus or directly into the stomach.
You can put food into a blender to make a slurry that is given through the tube.
Make sure your pet drinks enough water — he might not feel well if he’s dehydrated.
I recommend pet drinking fountains for a couple of reasons.
A harness with a handle to lift the chest or rump or a mobility cart can also help your pet move around better.
