The objective was to perform ocular biometry and ophthalmic examination in dogs of the French Bulldog breed. We evaluated 72 normal eyes of 36 healthy French Bulldog dogs, 20 males and 16 females, aged from 1 to 7 years. Ocular ultrasound was performed in B mode with a 10 MHz linear probe, and the following parameters of ocular biometry were evaluated: horizontal axial diameter (HAD) of the eye, lens thickness (LT), anterior chamber depth (ACD), and vitreous chamber depth (VCD). The ophthalmic exams performed were as follows: Schirmer Tear Test-1 (STT-1), rebound tonometry (Tonovet), Tear Film Break-up Time (TBUT), and Fluorescein Test (FT). The ocular biometry results (mean±SD) in millimeters were: 20.5 ± 0.6 (HAD), 3.8 ± 0.4 (ACL), 7.4 ± 0.3 (LT) and 9.4 ± 0.4 (VCL), and from the ophthalmic exams (mean±SD) were: 24 ± 3.7 (16.5-33.5) mm/min (STT-1), 20.0 ± 3.7 (13.5-27.0) mmHg (rebound tonometry), and 24.4 ± 6.3 (16-40) seconds (TBUT), and FT was negative in all dogs. The obtained results can serve as parameters of normal values of ocular biometry and ophthalmic exams for ambulatory routines, intraocular surgeries, and future ophthalmic studies in this breed.
Brachycephalic dogs have a normal lower jaw and a receded upper jaw, and these dogs are predisposed to nostril stenosis, elongated palate, tracheal hypoplasia and hyperthermia due to heat stress. Giventhese characteristics, these dogs are more predisposed to respiratory and cardiovascular disorders. The popularity of brachycephalic dogsthathave a greatertendency for cardiorespiratory disorders, such as French bulldogs,has increased recently; however, studies on the cardiorespiratoryand haematological parameters in this breedare lacking. Thus, the present study sought to evaluatethe cardiorespiratory and haematological parameters of healthy French bulldogs to standardize normal values forthisbreed. Thirty-six French bulldogs wereused without predilection for age or sex, and the following parameters were evaluated: temperature (T), heart rate (HR), respiratory rate (RR), erythrogram, leukogram, total plasma protein, plasmatic fibrinogen, blood platelet count, urea, creatinine, alkaline phosphatase (AP) and alanine aminotransferase (ALT). The mean and standard deviation wereas follows: T°C (38.3±0.4), HR (111.1±27.0) beats per minute, RR (54.8±32.5) breaths per minute, erythrocyte count (7.3±1.2x106), haemoglobin (16.9±2.8 g/dL), haematocrit (48.9±7.7%), MCV (67.6±2.4fL), MCH (23.3±0.7 pg), MCHC (34.6±0.8%), RDW-CV (9.3±0.9; 9.2-12.0%), total leukocytes (11009.7±2907.3/mm3), band neutrophils (250.0±260.4/mm3), segmented neutrophils (7094.4±2307.3/mm3), eosinophils (589.7±561.3/mm3), lymphocytes (2020.8±1457.5/mm3), monocytes (987.6±528.4/mm3), total plasma protein (6.9±0.5 g/dL), plasmatic fibrinogen (274.1±96.5 mg/dL), blood platelet count (366.4±88.5/mm3), urea (35.2±12.6 mg/dL), creatinine (0.8±0.2/mg/dL), AP (49.1±25.8U/L),ALT (36.2±12.3U/L). The haematological parameters and heart rate were within the normal values for the species, but the respiratory rate values (54.8±32.5 breaths per minute)were greater than the normal averageof10 to 30 breaths per minute. We conclude thatthehaematological parameters and heart rateof healthy French bulldogs arewithin the normal limit for dogs; however, the respiratory rate is above referencevalues, reinforcing the notion that dogs of this breed, although healthy,exhibitan increasedrisk of respiratory disorders
