canine Abs

Good day all.  I'm having some trouble locating Abs for canine leukocytes. 
 I did find a few useful ones at VMRD, but I can't seem to locate a CD3. 
Also, they have a "CD45-like" as opposed to just CD45.	I've used their 
"neutrophils" ab before with great success, but I have no experience with 
others.  I've also considered just trying anti-human abs from the usual 
suspects as I know that more often than not that works for our histo 
folks.	I would appreciate any info from those of you that have dog 
experience, especially insight into apparent lack of CD3 and "CD45-like" 
vs true CD45.

Thanks,

Dave
