Dog breast disease is a very headache, common breast diseases in dogs include mastitis, mammary tumors, etc. The pooper scooper should take appropriate diagnostic and treatment measures according to the specific condition of the disease. Mastitis canine mastitis, also called mastitis, is a disease that not only endangers the physical and mental health of the mother dog, but is also detrimental to the nursing puppy. It is an acute or chronic inflammation of one or more mammary glands that can occur simultaneously. This disease often occurs in lactating bitches. Etiology: Acute mastitis is mainly seen when the mammary gland is damaged or traumatized during suckling by the puppy, or when the milk accumulates during sudden weaning or when all the puppies die during lactation. The disease can also be secondary to a metastatic infection from acute uterine inflammation. The main pathogens of infection are streptococci and staphylococci. Chronic mastitis is most often seen in older dogs and may be related to hormonal imbalance. Symptoms: In the early stages of mastitis, the affected mammary glands are variously congested and red, the breasts are swollen and hard, warm to the touch, the lymph nodes on the breasts are enlarged, and lactation is reduced or stopped. As the infection progresses, systemic symptoms such as increased body temperature, depression, loss of appetite, and dehydration may occur. Mastitis may develop into a breast abscess, where the center of the swollen part begins to soften and fluctuate, and sometimes self-rupture of pus occurs. Chronic pustular adenitis is characterized by the formation of cysts in the breast tissue, which sometimes develop into tumors. Diagnosis: It can be based on trauma to the affected dog’s breast, as well as local signs of disease in the mammary gland. Treatment: Acute mastitis should be treated with antibiotics as early as possible, and the entire litter of nursing puppies should be weaned and hand-fed. Massage and milking the affected udder several times a day, and inject aqueous antibiotics into the milk pool via the nipple tube after milking, 2 to 3 times a day. Antibiotics should be used broad-spectrum, such as penicillin and streptomycin with ampicillin. Furans and sulfonamides are also available. For those who develop breast abscesses, the pus can be drained by incision at the softest point and flushed with penicillin saline. Circumferential closure around the mammary glands with 0.2% procaine hydrochloride solution has good efficacy. For breast pools with serious milk accumulation, in addition to milking, the therapy of hot compresses followed by cold compresses can be carried out twice a day. For dogs with systemic symptoms, infusion therapy should be used, paying attention to calcium supplements and vitamin C. For those who have formed mammary tumors, mastectomy for tumor changes is feasible. Prevention: 1. Keep the womb clean. 2. Shave the hair around the mammary glands and pay attention to the cleanliness of the mammary glands. Trim the toenails of the puppy to avoid scratching the mammary glands of the bitch while drinking milk. Mammary tumors Canine mammary tumors (CMT) are the most common tumors in female dogs. Malignant tumors account for approximately 50% of cases and most metastasize. Unspayed bitches are among those with a high incidence. The incidence in female dogs is about 2 per 1,000, of which 60% are malignant. There is no breed difference in the disease, as any dog can develop this neoplastic disease. Etiology: The increase in growth hormone production due to progesterone is accompanied by a parallel increase in blood levels of insulin-like growth factor I (IGF-I) and insulin-like growth factor II (IGF-II), which stimulates the proliferation of mammary cells. The hormonal regulation and autonomous expression of growth factors and their receptors may also affect the production of breast tumors, thus making the process of breast tumor production extremely complex. Symptoms: Breast tumors often occur at the penultimate 1st, 2nd and 3rd nipples, where there are more secretory epithelium, mucosal epithelium and cells, and the probability of malignant tumors is higher. Malignant breast tumors usually show red discoloration, elevated temperature, swelling and rapid growth in the local lesion area. Diagnosis: It can be determined based on the basic physiological values, visual examination, palpation, and the results of laboratory X-ray examination. Treatment: Surgery can be performed to remove the breast tumor and remove the ovarian uterus. 1. Preoperative preparation and anesthesia Intravenous placement of indwelling needle, saline to establish intravenous access, anti-inflammatory and hemostatic, pain relief, atropine. Propofol induced anesthesia, endotracheal intubation, inhalation anesthesia, cardioplegia and oximetry monitoring. 2. Bonding and surgical procedure After general anesthesia, the affected dog was supine and bonded, and the abdomen was extensively shaved and disinfected. Ovariohysterectomy was performed first, and the abdominal wall was routinely incised and the ovaries and uterine horns were ligated and excised bilaterally, with routine closure of the abdominal wall. The mammary tumor to be resected is made an ovoid skin incision about lcm away from the tumor, and the skin is continued to be incised to the fascia of the external abdominal wall, avoiding cutting into the breast tissue as much as possible. The tissue surrounding the inguinal lymph nodes is bluntly separated, the lymph vessels and their vicinity are ligated, and the inguinal lymph nodes are removed. The wound is flushed with saline, coated with some antibiotics (penicillin), the subcutaneous tissue is closed in layers with 3/0 PGA sutures and drains are placed, the skin is closed with nodal sutures, sterilized and bandaged, and the skin is wrapped with a 3-row bandage to compress the skin and reduce skin tension while preventing cavitation. Prevention: If the dog’s usual staple food is meat, then the probability of tumors will likely increase, so owners need to have some balance in the food they give their dogs. The dog’s chances of getting a tumor will also be greatly reduced if the dog is sterilized. If you’re a dog, you’ll be able to get rid of the tumors in the mammary gland before the first heat when your pet is young. Note that nursing bitches should stop nursing their puppies during the treatment period. Such milk will bring harm to the puppy, and the pet owner can find another female dog to nurse.
