Rocky is 14 and has been throwing up his meals mostly breakfast. He had stopped eating (Blue Buffalo) so I got sensitive stomach (Pro Plan). At first no problem now throws up but wants to eat. He falls and I watched and realized he was trying to walk on tops of feet. He turns into puppy when lizard runs in his path. He is my service dog but hasn't worn vest in 2 yrs because of fatty tumors on side. He doesn't seem to hear as well either. He is not in any pain. I have noticed he is drinking more water. I don't want to think of putting him to sleep. Please help I'm scared.
Rocky died congestive heart failure and herniated disk he was was 141/2 yrs old. Sorry about typing its thru tears. Thank you all.
