Welcome to JustAnswer! I am a licensed veterinarian and would be glad to help!
When did this start?
How many times per day is he vomiting?
Unfortunately - I am very concerned with this degree of vomiting.
You can certainly try a bland diet such as boiled chicken and rice (2/3 rice and 1/3 chicken). You can also consider giving 10mg of Pepcid A/C (famotidine) by mouth every 12 hours for 5 days for stomach upset. You can purchase this over the counter. BUT - If the signs do not resolve - or worsen - then I would see your primary veterinarian or go to the local ER.We really should make sure there is not a blockage with belly x-rays or other systemic causes for vomiting - considering not only belly x-rays but basic bloodwork to check cell counts and organ values as well can see secondary complications such as dehdyration from all the vomiting.I hope this information helps!_____________________________________________________________________Please click "ACCEPT" if the information I have provided has been of help so I receive credit for my work.
