Hi! My dog has vomit a few days already.After a visit to vet's clinic,the times she vomit has decrease from 3 times a day to now once a day but not cure.She is very tired and always sleep.She want to shit but nothing comes out and when she can do it the shit or not in shape,there are mostly in liquid type.She don't want to eat now but just drink water.Yesterday morning she eat some porridge but had vomit in the afternoon.This morning she eat some tuna and drink some glucose.And now i discover that i will hear some sound like she is grinding her teeth when she is drinking or eating.She is 11 years old now.The doc from vet's clinic said that she is old and all this will come to her and this is normal.Is this true?She is suffering in this,how can i cure my dog?please help me. Thank you !!
