Up in the clouds
To be honest, I don't understand why the dogs must be kept in a kennel rather than getting sent home under the condition that they must be leashed and muzzled when in public. If there were any concerns, presumably they could do a behavioural assessment to check that they're fit to return home.
If my dog were involved I would be pushing for that tbh. No matter how long it takes for test results to come back the forensic scientists must surely have all the info they need by now and if they haven't the dogs could be taken to them for further samples to be taken.
