The aim of the study was to determine normal values of tear production in crossbred dogs using the standardized absorbent paper points test (SAPPT) in comparison with the Schirmer’s tear test (STT). A total of 33 dogs (66 eyes) of dolichocephalic skull type, between 2 to 6 years of age and of medium size (15-24 kg) were used. The mean tear production value by SAPPT was 20.85 ± 1.44 mm/min (range: 18-24) and by STT was 18.05 ± 1.58 mm/min. A positive weak correlation was found between SAPPT and STT values.

The objective of the study was to evaluate the effect of a physiotherapy treatment (massage, thermotherapy, electrotherapy and ultrasound) in the recovery of canine patients with hind limb injuries. The dogs (n=15) were of both sexes, with ages ranging from 5 months to 12 years, who attended the veterinary consultation with claudication of the hind limbs due to hip dysplasia, spondylarthrosis and traumatic neuropathies. The animals were treated for up to a maximum of 12 sessions, where the first six sessions were twice a week and the other six were once a week. Twelve of the 15 patients recovered favorably and three elderly patients did not respond to the treatment. The application of physiotherapy had an 80% effectiveness in canines with hind limbs problems.

INTRODUCCION: Neospora caninum, es un protozoario intracelular obligatorio y cosmopolita, causales principales de abortos bovinos a nivel mundial (Dubey, 2003), pertenece a la familia Apicomplexa, donde también están los géneros Toxoplasma, Isospora y Sarcosystis que se diferencian por el tipo de huéspedes que intervienen en su ciclo evolutivo (Dubey et al., 2007). En 1998 McAllister y col. completó el ciclo biológico tras descubrir al perro como hospedero definitivo. La Neosporosis es considerada una enfermedad importante debido a las infecciones reportadas en varios países, incluyendo Perú (Rivera et al., 2000). La Cuenca Lechera de Lima no es ajena a los problemas reproductivos y la presencia de N. caninum ,ha sido demostrada en varios establos (Casas, comunicación personal) desconociendo la fuente de infección. Dubey et al., 2003 menciona que las técnicas serológicas de d...
