犬細小病毒感染的狗狗會出現精神沉鬱、不食、嘔吐、腹瀉。病初糞便呈稀狀，隨病狀發展，糞便呈咖啡色或番茄醬色樣的血便並帶有特殊的腥臭氣味。後期嚴重脫水，眼球下陷、鼻境幹燥、皮膚彈力高度下降、體重明顯減輕的症狀。建議你用等滲的葡萄糖鹽水加入5％碳酸氫鈉注射液給予靜脈注射。可根據脫水的程度決定補液量的多少。然後配合消炎、止血、止吐、慶大黴素1萬單位／千克體重，地塞米鬆0.5毫克／千克體重混合肌肉注射，或卡那黴素5萬單位／千克體重加塞米鬆混合肌肉注射。維生素K11毫克／千克體重，Vk30.4毫克／千克體重，混合肌注。（注意：如果不是專業的獸醫，請不要隨便給寵物注射藥物，需要專業的獸醫操作）另外還有狗狗吃骨頭刺到胃了、肚子裏有寄生蟲、還有是腸胃炎型狗瘟等都會引起狗狗拉稀便血，如果狗狗情況嚴重一般情況還是建議到寵物醫院就診，以免錯過治療時間。
以下是google 英文翻譯：
Dogs infected with canine parvovirus will have depression, loss of food, vomiting, and diarrhea. At the beginning of the disease, the feces are thin, and with the development of the disease, the feces are brown or ketchup-like bloody stools with a special smell of odor. Severe dehydration in the later stage, the eyeball subsided, the nasal environment was dry, the skin elasticity was lowered, and the body weight was significantly reduced. It is recommended that you use an isotonic glucose solution with 5% sodium bicarbonate injection for intravenous injection. The amount of rehydration can be determined according to the degree of dehydration. Then combined with anti-inflammatory, hemostasis, antiemetic, gentamicin 10,000 units / kg body weight, dexamethasone 0.5 mg / kg body weight mixed intramuscular injection, or kanamycin 50,000 units / kg body weight dexamethasone mixed intramuscular injection. Vitamin K 11 mg / kg body weight, Vk30.4 mg / kg body weight, mixed intramuscular injection. (Note: If you are not a professional veterinarian, please do not inject drugs into your pets, you need a professional veterinarian.) In addition, there are dogs that eat bones to the stomach, parasites in the stomach, and gastroenteritis. It will cause the dog to pull the blood in the stool. If the dog is in serious condition, it is recommended to go to the pet hospital for treatment, so as not to miss the treatment time.
但是你已經做了抽血，是不是可以排除了？
另外， dog puppy不懂事， 很喜歡什麽都要拿來啃啃， 容易咬碎了家俱， 玩具，誤吞碎片。吞了金屬製，塑料，木頭，不僅可能堵塞，還可能碎片不規則，帶尖的，劃傷內部。 仔細查看，推敲。 同時詢問vet，與vet商量下一步。
還有千萬不要不小心把人的藥掉地上。
再有，我家後院植物和花的種類繁多，留心puppy 誤食中毒， 共勉。
理解你的擔心。我相信dog比較皮實， 自我恢複能力較強。
