A higher frequency of canine silica urolithiasis is found in Mexico, unlike <1-8% in other countries. The causes and risk factors for this pathology are unknown. However, we consider the consumption of high amounts of silica from the solid diet or dissolved in water as the only hypothesis.

Methods: This study analyzed clinical specimens of feline urolithiasis submitted to our laboratory in the period from 2006 to 2017. The mineral composition of the uroliths was determined by qualitative and quantitative mineral analyses, performed by stereoscopic microscopy and infrared spectroscopy.
Urinary bladder worm infection is relatively uncommon in pet dogs and cats in the Americas. This report describes the diagnosis of lower urinary tract infection by Pearsonema plica in two asymptomatic dogs and P. feliscati in a cat with lower urinary tract clinical signs diagnosed between 2002 and 2015, and the first report of this type of parasitism in domestic small animals in Mexico at an altitude above 2600 m above sea level.

The mechanisms by which obesity causes HTN are complex and involve several organic mechanisms. The objective of this study was to determine the correlation between obesity to HTN in dogs in accordance with recent international protocols (systolic blood pressure >160 mmHg) relating to age, genre, gonadal status, breed and other diseases commonly associated with HTN.

Here, we evaluated the clinical and immunopathological alterations developed by mongrel dogs experimentally infected with different infective doses (2,000, 20,000, and 200,000 metacyclic trypomastigotes of Sylvio X10/4 strain kg(-1) via intraperitoneal). Clinical and electrocardiographic parameters, as well as antibody production and pathologic lesions were evaluated.
