It has the effect of paralyzing roundworms, so that roundworms cannot attach to the intestinal wall of the host and are excreted with intestinal peristalsis. Based on the physiological characteristics of puppies and big dogs, combined with the efficacy and economic conditions (how much RMB), I recommend: Under normal circumstances, puppies can take children's deworming drug - Pagoda Sugar, one pill once a day for 3 days ; For large dogs, take 2 tablets of Intestinal Worm Cleanser. If the baby is born with tapeworms, take praziquantel, 10 mg/kg of body weight, once, and the dosage for puppies should be halved. Intestinal Worm Cleanser is enough to deal with intestinal parasites such as roundworms, hookworms and pinworms! Generally, the dosage of Intestinal Chongqing for small dogs is 50 mg/kg. Large dogs weighing about the same as adults should take two tablets at a time, and medium-sized dogs should take one tablet at a time. Some friends have asked: Why can’t dogs excrete intestinal worms after eating them? Because Intestinal Chongqing can be metabolized in the body to produce sulfone and sulfoxide, the latter can destroy the worm body and decompose it into fragments under the action of digestive juice. In other words, the worms become your snacks and are digested. If you like to see insects crawling around, use anti-insect spirit.
