Our dog is not well

[exrtnz]

Hi , our dog is usually full of life and fit and healthy ,but just recently he has not been eating and has been spewing all the time just watery stuff ,also has a real lack of energy. Im away working overseas and left at the start of this week, we thought he mightve stopped eating because of that but now he has been spewing and little energy the missus brought him into the vet. Luckley the vet is only 400meters away as she hasnt got her licence. While in the vet clinic he spewed twice and the took him in straight away and took Xrays. They found a lump in his stomach and think it might be something hes eaten. Hes on a drip as they said hes very dehyrated probably from the spewing. Its cost $600 so far but money isnt an option as hes part of the family.
He went in there yesterday , his weight has dropped nearly 2kgs when they weighted him .Will send a update when I hear further on him.
