“…Another potential adverse health effect associated with RMBDs was identified in a recent report. 83 Authors of that report 83 identified and described 12 dogs with elevations in serum thyroxine concentration (6 of which had clinical signs of hyperthyroidism) caused by eating an RMBD. All dogs had thyroxine concentrations within the reference range after the diet was changed.…”

“…Numerous studies (Freeman et al, 2013; Freeman, Janecko & Weese, 2013; Freeman & Michel, 2001; Kohler, Stengel & Neiger, 2012; Lenz et al, 2009; Leonard et al, 2011; Stiver et al, 2003; Strohmeyer et al, 2006) have reported the risks of feeding RAP diets, in particular bacterial disease, parasitic disease, and nutrient imbalance. Pathogenic Salmonella spp., Listeria monocytogenes, Campylobacter spp., Clostridium spp., and Escherichia coli ( E. coli) have been associated with feeding RAP diets.…”

“…In addition to zoonotic bacteria, pets fed raw meat may also contract zoonotic parasitic diseases (including toxoplasmosis and echinococcosis) (Araujo et al, 1975; Elmore et al, 2010; Jokelainen et al, 2012; Moro & Schantz, 2009; Schwabe et al, 1972; Strohmeyer et al, 2006). Raw diets (both commercial and homemade) may also be nutritionally inappropriate for the species or life-stage to which they are fed (Dillitzer, Becker & Kienzle, 2011; Freeman & Michel, 2001; Kerr et al, 2013; Kohler, Stengel & Neiger, 2012; Taylor et al, 2009; Zeugswetter, Vogelsinger & Handl, 2013). …”

BackgroundThe practice of feeding of diets containing raw animal products (RAP) to pets (dogs and cats) is discouraged by veterinary organizations and governmental public health organizations. Nevertheless, the practice of feeding RAP to pets is increasing in popularity. Pet owner motivations for feeding RAP diets to pets have not been explored and the benefits of RAP diets remain largely anecdotal. We hypothesized that pet owners feeding RAP diets would not rely on veterinary advice in choosing their pet’s diet. We also hypothesized that these owners would have lower levels of trust in veterinary advice with respect to nutrition relative to pet owners not feeding RAP.MethodsAn anonymous web-based survey was developed to identify pet owner motivations for feeding RAP diets, and to characterize the veterinarian-client relationships of individuals feeding RAP diets.ResultsThere were 2,337 respondents and 2,171 completed surveys. Of survey respondents, 804 reported feeding RAP at the time of the survey. While 20% of pet owners feeding RAP relied on online resources to determine what or how much RAP to feed, only 9% reported consulting with a veterinarian in making decisions about feeding RAP. Pet owners feeding RAP reported lower levels of trust in veterinary advice both ‘in general’ and ‘with respect to nutrition’ than pet owners not feeding RAP. Most pet owners reported that a discussion regarding their pet’s nutrition does not occur at every veterinary appointment.DiscussionPet owners feeding a RAP diet have lower trust in veterinary advice than pet owners not feeding a RAP diet. Owners feeding RAP are more reliant on online resources than their own veterinarian in deciding what and how much RAP to feed. Pet owners perceive that nutrition is not discussed at most veterinary appointments. Therefore, there is room for improvement in the veterinarian-client communication with regards to nutrition.

“…To the authors' knowledge, this is the second report of food induced hyperthyroidism in dogs. The fi rst publica-tion, a retrospective study from 2006 to 2011, appeared during the writing of this paper and described 12 dogs with hyperthyroxinemia most likely caused by feeding thyroid tissue from animal origin (Köhler et al, 2012). Thyroid hormones are orally active and feeding fresh thyroid glands was one of the fi rst effective treatments of hypothyroidism in human patients (Mackkenzie, 1892).…”

“…Spuriously elevated thyroxine concentrations are possible in case of anti-thyroxine antibodies interfering with specifi c immunological assays (Choi et al, 2006) and prolonged storage of serum at high temperatures (Behrend et al, 1998). Recently Köhler et al (2012) described a possible new cause of hyperthyroxinemia in 12 dogs in a retrospective study. Eight of these dogs were fed the "bones and raw food" (BARF) and 4 a commercial diet.…”

Two female spayed dogs belonging to the same owner were admitted for further examinations because of clinical signs and laboratory values compatible with hyperthyroidism. Sonography of the ventral aspect of the neck revealed small thyroid glands in both dogs. The hypothesis that the dogs suffered from alimentary hyperthyroidism caused by feeding head meat containing thyroid gland tissue was confirmed by consultation of the slaughtering plant, determination of iodine concentrations in deep-frozen samples and hormone measurements in 5 other dogs receiving head meat from the same supplier. After changing the diet, thyroxine concentrations declined and clinical signs were no longer observed.
