peekapoo vomitting white

Question
my dog theo is 2 yrs old, male peekapoo,
for 3 days he has been coughing and vomitting white -watery-foam. very weak, tired, and not himself, to my knowledge he has not gotten into any type of poison. what should i do, or what is it?? please help.  

Answer
Hi Patti,

You need to take Theo to a Veterinarian. If he is weak, he is probably dehydrated. He may have some type of stomach "flu" or some other disorder that needs medication.  If he continues this way he is going to die. He needs professional help.  We are NOT Vets and cannot give you the help that you need as he needs meds and probably fluids at this point.  I hope he will be ok.

God bless,
Becky
