I am really concerned about this product. I have a 15 year old terrier mix. He is slowing down and has arthritis issues. I started him on this supplement 6 days ago. Everyday he has been vomiting and gagging around 3-4 hours after eating since I started him on this. I feed him twice a day. There was no instructions to splitting the dose. At first I gave all in the morning. Then I split it, half morning and half evening. He is under 30 pds so just half scoop twice a day. Is this a normal thing for his system to get use to?
