Your replies have been most helpful, thorough, and very educational for which we are most grateful.
In searching prior vet visits, when the most comprehensive blood work panel was done back in 12/12, it revealed a cholesterol of 274,Triglycerides of 75, Glucose 107, T4 1.8, with the HGB still running high 19, and HCT 54. All of his other prior HGB and HCT tests have also run consistently around 19 and 55. Albumin also tends to run in 4.2 Range. Additionally, back in 2011 a vet did an ACTH test which we were told was negative.
With regard to your specific comments about if this was your dog/ patient, and that steroids can elevate cholesterol, LO AND BEHOLD, RB did get a 2mg injection of VETALOG for his allergies about 3 days or so before this reading!
So, any chance you have an office in either Michigan or Florida? Compounding our situation medically, is that we divide our time between these two states and thus have two vets providing treatment and thus we lack uninterrupted continuity of care, and at times receive differing perspectives.
So, unless we hear back from you with what appear to be other great insights, we will repeat his cholesterol and triglyceride blood work and ensure that he has had nothing for a full 12 hours before. We will also work on reducing the fat content of his grain free lamb kibble, perhaps by going back to a mix of the grain free (16 fat) and lamb and rice (11 fat) to bring the final total down within the recommended range 0f 12-15. We were doing this before the Cal Natural recall with no apparent adverse consequences.
Thank you again for being so responsive and providing such a comprehensive reply!
