The 8th Edition of the Guide for the Care and Use of Laboratory Animals clarified its language regarding housing social species, specifying that, “Single housing of social species should be the exception…”. This is a...

Bailey, C. 2017. Refinements in housing during data capture in long term Safety Pharmacology dogs. Animal Technology and Welfare 16(2), 147-149.

Dogs are individually housed when collecting data for ECG studies to avoid any cross talk between transmitted signals (generally for a 24 hour recording period). Each implant is set at a certain frequency which transmits...
