Comparative Effects of Aminophylline, Caffeine, and Doxapram in Hypoxic Neonatal Dogs Born by Cesarean Section Júlia Cosenza Mendonça, Keylla Helena Nobre Pacífico Pereira, Gleice Mendes Xavier, Kárita da Mata Fuchs, Thaís Gomes Faustino, et al. Animals, 2025 Background: Perinatal hypoxia is a leading cause of early mortality in canine neonates and accounts for over 90% of early deaths in canine neonates. Respiratory depression may result from dystocia, prolonged labor, or anesthetic protocols used during cesarean delivery, requiring rapid pharmacological support. This study evaluated the effects of aminophylline, caffeine, and doxapram on clinical and biochemical viability parameters in hypoxic neonatal dogs. Methods: Forty-five puppies born via elective or emergency cesarean section were included, of which 35 exhibiting cardiorespiratory depression (heart rate ≤ 180 bpm, respiratory rate < 15 movements per minute, Apgar score < 7, and reflex score < 3) were randomly allocated into aminophylline group (AG; n = 12), caffeine group (CafG; n = 11), or doxapram group (DG; n = 12). Ten clinically healthy neonates constituted the physiological control group (CG). Apgar score, neonatal reflexes, lactate, blood glucose, oxygen saturation, blood gas parameters, and cardiac troponin I (cTnI) were evaluated immediately after birth (M1) and 10 min following treatment (M10). Results: No significant differences were observed in laboratory parameters among groups (p > 0.05). Although all evaluated drugs improved clinical status by increasing heart rate, respiratory rate, and reflex scores, caffeine produced the greatest enhancement in vitality. The Δ Apgar score showed a significant difference between CafG and DG (p = 0.0095), while no statistical differences were detected between AG and CafG (p = 0.08) or between AG and GD (p = 0.60). Conclusions: Aminophylline, caffeine, and doxapram supported postnatal resuscitation in hypoxic neonatal puppies; however, caffeine demonstrated superior improvement in Apgar recovery, suggesting its potential as a preferred pharmacological adjunct in neonatal canine resuscitation protocols.

Impact of Delivery Method on Serum Cortisol Levels and Neonatal Outcomes in Canine Cesarean Sections Renatha Almeida de Araújo, João Domingos Rocha-Júnior, Jaqueline Tamara Bonavina, Melissa de Oliveira Bianchini, Samara Beretta, et al. Animals, 2025 In this study, thirty female dogs, aged one to five years and varying in weight, in the last week of gestation were evaluated. The animals were divided into two groups: GC, which comprised twenty-two bitches undergoing elective cesarean section, and GD, which consisted of eight dogs requiring therapeutic cesarean section as a treatment to dystocia. We found that cortisol levels in the amniotic fluid were significantly higher in pups delivered via elective cesareans (mean: 9.86 ng/mL) compared to those from therapeutic c-sections (mean: 4.11 ng/mL). This observation contrasted with previous studies that reported lower cortisol levels in elective procedures, suggesting complexities in the physiological responses to different delivery methods that warrant further investigation. Notably, our study observed no significant association between amniotic fluid meconium presence and other distress markers, indicating that meconium may be more closely associated with fetal maturation rather than distress (p > 0.05). Neonatal viability (Apgar score) revealed that 92.86% of the neonates from elective procedures demonstrated no distress shortly after delivery, contrasting with 56.25% in therapeutic c-section. Fetal distress can be a direct consequence of dystocia caused by various stressors, such as pain and hypoxia. These factors can impair the fetus’ ability to adapt to extrauterine life, often leading to lower Apgar scores. Notably, neonatal weight was directly related to fetal cortisol levels, while no significant associations were noted between the litter size or birth order and cortisol concentrations, irrespective of the delivery type. These findings underscore the need for ongoing investigation into the relationships between cesarean delivery types, maternal and neonatal stress markers, and resultant health outcomes, aiming to enhance care strategies for expectant canine mothers and their puppies.
Clinical Approach to Cleft Lip and Palate with or Without Surgical Correction in Ten Brachycephalic Puppies Gleice Mendes Xavier, Keylla Helena Nobre Pacífico Pereira, Kárita da Mata Fuchs, Júlia Conseza Mendonça, Rebeca Bastos Abibe, et al. Veterinary Sciences, 2025 Congenital defects are among the leading causes of neonatal mortality in small animals. Among them, cleft palate is one of the most commonly found malformations in dogs. Appropriate clinical management and surgical correction are determining factors for the survival of puppies affected by this alteration. Thus, the objective of this study is to describe 10 clinical cases of successful clinical management of cleft palate, highlighting the therapeutic strategies used, the results obtained, and the evolution of patients after treatment. Ten neonatal dogs of three breeds were treated by the Small Animal Reproduction Service of FMVZ, Unesp—Botucatu: French Bulldog (6), Pug (3), and American Bully (1) presented with cleft palate at birth or during the first week of age. Patients underwent clinical and nutritional management, in addition to immunological support. At four months of age, the patients underwent medially positioned flap repair. The animals were fed via an esophageal tube for 10 days after surgery. The clinical management proved to be effective since, throughout the follow-up, the animals showed good development and did not present complications arising from the cleft palate, and the surgical procedures were successful, restoring the quality of life of the animals.
Vaginal Seeding: Is There Any Positive Effect in Canine C-Sections? Samara Beretta, Renatha Almeida de Araújo, Melissa Oliveira Bianchini, Jaqueline Tamara Bonavina, João Domingos Rocha-Júnior, et al. Animals, 2025 This study aimed to scrutinize variations in the intestinal microbiota of neonatal dogs born through natural birth versus elective cesarean section, focusing on evaluating the influence of vaginal seeding on the microbiota of cesarean-born neonates. Samples were collected from cesarean-sectioned females before anesthesia and from naturally birthing females during prodrome signs, along with neonates at eight time points from birth to 15 days of age. In the cesarean section group, seeding was performed in half of the neonates (cesarean section seeding group; seeding consisted of gently rubbing the gauze, obtained from the mother’s vagina, onto the mouths, faces, and bodies of the newborns), while the other half underwent microbiological sample collection without seeding (cesarean section group). Another group (normal birth group) consisted of naturally born neonates. Microbiota analysis included counting for enterobacteria, Staphylococcus spp., and Streptococcus spp. The results suggested that vertical transmission played a crucial role, but the method of birth did not emerge as the primary determinant of observed differences. Under study conditions, vaginal seeding failed to effectively modulate the microbiota of neonates born through elective cesarean section. Further investigations into the gut–brain axis are suggested for understanding factors influencing the initial development of the canine intestinal microbiota in neonates born through different delivery routes.
Safety Assessment of an Oral Therapeutic Dose of Firocoxib on Healthy Horses Renatha A. Araújo, Nathali A. A. Sales, Roberta C. Basile, Walter H. Feringer-Junior, Maricy Apparício, et al. Veterinary Sciences, 2023 Firocoxib is a non-steroidal anti-inflammatory drug specifically formulated for veterinary medicine and selectively acts on inhibiting the cyclooxygenase 2 enzyme (COX-2). This study evaluated the possible adverse effects of administering oral therapeutic firocoxib on gastric mucosa, hematological parameters, coagulation cascade, and hepatic and renal biochemistry in healthy horses. Nine clinically healthy Arabian horses, approximately 9 years old, received 0.1 mg/kg of oral firocoxib for 14 days. The gastroscopic examination was conducted 1 day before starting treatment (D0) and two days after the last blood collection (D23). Venous blood samples were obtained for laboratory tests on day 1, immediately prior to the initiation of treatment (D1), after 7 and 14 days of treatment (D7 and D14), and 7 days after the conclusion of treatment (D21. No changes were found in the gastroscopic and hematological tests. Coagulation and serum biochemistry levels remain between these species’ average values. However, the increased activated partial thromboplastin time (aPTT) and prothrombin time (PT) indicate reduced blood coagulation capacity, which contradicts the expected effect of treatment with selective COX-2 inhibitors, as these drugs theoretically promote coagulation. Administering firocoxib to horses is safe as it does not cause significant adverse reactions. Therefore, it is a suitable option for managing inflammatory conditions in these animals with attention to an unexpected adverse anti-coagulopathy effect, and further study is warranted.
