Absolutely. Cattle and horse born diseases spread all along the trail. Of course with any travel some human illnesses would travel too. Look at how smallpox spread to the Indians as explorers and traders moved west. Cattle would also carry seeds for noxious (unwanted/hard to kill) weeds and vermin. For many years cattle coming from Mexico had to be dipped in pesticides to kill the lice and tics before they could be brought to the US.
Spread disease
Cattle Ranching started in Texas and spread all throughout the West.
It is believed that grasshoppers do spread disease. In the past, it has been proven that grasshoppers spread the VSV virus to cattle and horses.
A nasty disease called the Texas Fever.

Cattle trails were commonly found in the 19th century in the western United States, particularly in states like Texas, Kansas, and Nebraska. These trails were used to drive cattle from ranches to railheads for transportation to markets. Many of these historic cattle trails have since been incorporated into modern roads and highways.
The cattle trails came to an end primarily due to the expansion of the railroads, which provided a more efficient means of transporting cattle to markets. Additionally, the overgrazing on the trails led to depleted grasslands, and the severe winters of the late 1880s significantly reduced cattle herds. Increased fencing due to the Homestead Act also limited the open range that cattle drives relied upon, ultimately transforming the cattle industry and leading to the decline of the traditional cattle trails.
If by trails you mean cattle drives, the purpose was to move large herds of cattle to the nearest railroad stop so the cattle could be shipped to other parts of the country, usually larger cities in the east.
Anaplasmosis is not a disease in dogs, nor is it spread by saliva or by feed in either cattle or dogs. It is a blood-borne infectious disease in cattle caused by rickettsial bacteria of the Genus Anaplasma. It occurs more commonly in the subtropical and tropical areas and, though not contagious, can transmitted by ticks that feed on the blood of cattle. It can also be spread by contaminated needles, dehorning equipment, castrating knives, tatooing equipment and biting flies and mosquitoes.
