My dog reccey passed away 4 weeks ago.he was always a big eater.he had his shots,then he started losing weight,he went from 14 to 9 pounds in 3 weeks.he would paw at his mouth when he tried to eat.sometimes he would paw at his mouth when I would just show him food.he was vomiting a clear liquid.his tonge was pale.I took him to the vet they did bloodwork.checked his mouth,gums,said nothing was wrong.they said I had to force him to eat.we tried everything,one time he would a eat a few bites next time he would not.I took him back to the vet,they did another bloodwork,ckecked his mouth again.they said nothing was wrong,just a little anemic.but that was from not eating.that was on a Monday,on Saturday the same week he was vomiting that clear liqued a few times could hardly stand up.I took him to the vet again his temp.was 90 .the vet kept him that night,the vet said he tried to save reccey but he didn't make it. Do you have any ideas what was wrong with reccey?
