I have been so worried about bringing new puppy at home but still managed to get one. Since I have 3 older dogs, two dogs are just outside for guarding purposes and one dog stays inside the house for about 8months already.. When I brought my new puppy at home, he already had 2 5in1 vaccine at 4 weeks den 6 weeks respectively, but his new vet insisted to start again from the first dosage (too long to discuss). His deworm is also updated. Yesterday I noticed that he had no energy like before and didnt ate his lunch and dinner.. Then he started to throw up his food after eating his breakfast that day.. He had 3 episode of vomiting and one watery stool that has also hard stool on it. I am worried because Sept 30, 2016, he got his 3 dose of vaccine (technically), the pattern was 4th, 6th, 10th week (again his new vet suggest that we start from 1st dose, so he still have to undergo 3 more visit for 5in1 vaccine). Since my puppy had his vaccine on Sept 30, so I decided to let him play with my 8months old puppy for quite a few minutes to drain his energy because he bits a lot cause mybe he cant do some exercise inside my room and inside his crate.. PLEASE IM NOT IN A GOOD SHAPE TO CONSTRUCT A GOOD PARAGRAPH, SORRY FOR MY ENGLISH AND I APPRECIATE ANY HELP.. CONCERNS MIGHT BE PARVO OR OVERDOSING with HIS SUPPLEMENTS AND VITAMINS.
