Dog brain scan suggests dogs see actions more that objects

While Dr. Doolittle’s dream remains elusive, advances in brain scanning and analysis have opened a window into how dogs’ brains reconstruct what they see. Researchers at Emory University found evidence that we should probably be using more verbs when overdubbing our dog’s antics.

Black soldier fly larvae calcium low for leopard geckos

Black soldier fly larvae (BSFL) have grown in popularity for leopard geckos because they have a higher calcium concentration than mealworms and crickets.

Black soldier fly larvae (BSFL) have grown in popularity for leopard geckos since they have a higher calcium concentration than mealworms and crickets. Long-term feeding of BSFL without vitamin supplementation or variation could result in deficiencies. Reptile supplement makers may continue to market their products as BSFL become more common in the reptile food market.

Salmonella defense boosted 475-fold in raw dog food

More than six decades ago, early moist pet foods used lactic acid to prevent spoilage by mold and other microbes. In the growing raw pet food trend, lactic acid may continue to help producers by fighting Salmonella.

A group of researchers used lactic acid in raw dog foods as the products underwent high-pressure processing. Find out what happened.

Pet food growth may outstrip animal protein supply

Animal protein production bottlenecks were only one of the supply chain issues facing the pet food industry now and in the near future, according to researchers in their examination of the interplay among human and pet food ingredient demands.

Toxic pet food contaminants: Arsenic, BPA, PCB, aflatoxin…

With climate change and shifting growth patterns for crops, aflatoxin may become even more of an issue in the future.

In the production of pet foods, no different than human foods, there are a number of compounds that make their way into the food that aren’t a part of the formula/recipe or stated on the ingredient listing.

Antibiotic-resistant germs grown from pet food in Europe

Antibiotic-resistant Enterococcus bacteria, including vancomycin-resistant strains, most frequently infect hospital patients and people with immune system issues.

Microbiologists grew antibiotic-resistant Enterococcus bacteria found in pet foods bought in Europe. Although pet food hasn’t been documented passing these germs to people, a reservoir of antibiotic resistance genes could be created in the gut of dogs.
