My poley jill has twice caught the cold from me when i had it and that was even with me having limited contact with them . A had to give all 4 antibiotics syringe fed a know 1 thing they didnt like it but it did the trick . Can remember the vet saying there hardy things but there either fit and well or they go down hill extremely quick . Just a reminder to you lads if your not well cold, flu have minimal contact with them as they can catch it off you . Ideation a hope your little fert pulls through for you atb fv
