Canine herpes virus is an enveloped virus, which can be transmitted by transplacental, venereal (semen, vaginal secretions) and oro-nasal routes.
It is therefore a sexually transmitted disease.
Abortion products (fetuses, fetal envelopes) can also be contaminants.
Juvenile vaginitis or prepubescent bitch vaginitis is an inflammation of the vagina in a puppy, sometimes as early as 6 to 8 weeks of age.
The disease often goes unnoticed by owners and is a diagnosis made by the veterinarian using the first vaccines between 2 and 4 months of age.
No racial predisposition has been reported.
It is a defect in the descent of one or both testicles into the scrotal pocket.
At birth, the testicles are located near the inguinal ring and at 5 weeks they are already normally in place.
An absence of testicles at 8 weeks is considered abnormal (delayed implantation), but it will take six months to legally diagnose an ectopic testicle. Beyond six months, whatever the breed, this is an unacceptable defect in dogs.
The modalities of artificial feeding are a source of concern and often misunderstanding.
The stakes are high. Any error can have serious immediate but also long-term repercussions (immunity, digestive, growth, psychological development, etc.).
It is a dropsy of fetal tissue in puppies that causes generalized subcutaneous edema associated with varying amounts of fluid in the abdominal and thoracic cavities. Two entities are described: congenital anasarca and congenital lymphatic edema (CLO).
This is a difficulty of locomotion observed in puppies from 2 to 4 weeks of age, and exceptionally in kittens that are unable to bring their limbs under them.
Although no specific cause has been isolated, several hypotheses are put forward: overweight secondary to overconsumption, unsuitable nursing zone (smooth ground without adherence or too high a temperature to promote immobility), delayed maturation of the nervous system (myelination of peripheral nerves), taurine deficiency, genetic cause, herpesvirosis, lack of selenium absorption…
It is a bacterial infection or poisoning by puppy/kitten bacteria through breast milk.
The syndrome is common after “careless” use of antibiotics in the postpartum period (see below).
The bacteria encountered (E. Coli, hemolytic Streptococci, Staphylococcus,…) most often come from mastitis (clinical or subclinical), uterine infection (placental retention, dystocic delivery) or vaginal postpartum.
It is a highly contagious respiratory disease, frequently encountered in dogs, especially young dogs, with significant morbidity but low mortality.
The main etiological agents involved are: Bordetella bronchiseptica, canine parainfluenza virus, canine adenovirus type 2 (CAV-2), canine herpesvirus, and canine reovirus.
Transmission is mainly through aerosols. This is not an unacceptable defect.
It is a severe gastroenteritis, highly contagious, often fatal, associated with marked leukopenia.
Disease caused by feline parvovirus (FPV), a naked virus that is highly resistant in the environment (several months).
Contamination is carried out orally and nasally.
The virus has a high tropism for cells with high replication (enterocytes, bone marrow cells, lymphoid organ cells): it causes cell necrosis by apoptosis, and therefore severe diarrhea, leucopenia and lymphoid depletion.
