I have not been into his office, but have talked to him on the phone and he has helped me with a couple of problems with the geese. A few years ago, in the spring some of the geese were gettting sick and a couple even died. It was one of the real wet springs with lots of rain. There was grass in the pasture that had grown tall the previous summer and the tops died, leaving cllumps of dead grass with green grass starting to grow under that mass. With all of the rain, mold was growing under there also with the green growth. So the geese were eating mold along with the new green growth. Mold is deadly to geese. I had gone out in the pasture, realized what was going on, did some internet research, but was not sure I had it figured correctly or what to use to medicate them. All I had was Duramycin 10. After calling every vet in the area and being told there was NO bird vet in the area, I someway heard of Dr Mendoze and called him. He confirmed it sounded like mold and that the Duramycin should work, and if not I could get something else from him. Thankfully the Duramycin did work, and the geese that were showing symptoms got well.
The other incident was when one of the older ganders developed a prolapse. Again, I did the internet research, but was not sure that what people said to do was correct. I called him, he confirmed what was happening and what I should do. It was so nice to have someone with knowledge confirm what I had found out and be willing to offer advice. It is also great to know if something comes up I can't figure out, he is there.
