The golden retriever puppy is so small. Are they only two months old? I don't know if it's true or not after three shots of vaccine.

They seem to be only two months old, and vaccination usually starts from one and a half months to two months. Immune vaccines include three doses of vaccine and one dose of rabies vaccine. Generally, you can be vaccinated against infectious diseases after 45 days. Usually most of them are six beats. The first immunization is three injections, and rabies vaccine is injected every 20 to 2 1 day. I think I lied to you. Try again. Some dogs may feel slightly uncomfortable after vaccination, because the vaccine itself is a virus with weakened invasion ability. Some dogs may have symptoms such as poor appetite, listlessness and lethargy after vaccination, but as the dogs get used to it, they will be fine in 1-2 days, and their bodies will gradually return to normal. Some probiotics can be added to the water that dogs drink, which can improve the dog's anti-stress ability and recover quickly.
