How's the pup this morning, Maria?
For future reference:
When concerned about infection I use Septi-Cleanse, a veterinary antibiotic cream that I get from the US. But for minor cuts most of the time I simply clean the wound with warm water, and keep an eye out for redness, swelling or continued bleeding. Cuts that continue to bleed usually require veterinary attention.
When in doubt, I speak to a vet before using anything. Often simply cleaning the wound is sufficient until I can confirm what I need to do.
By the way, a very handy resource is Vetpharm, the compendium of veterinary medicines allowed (or disallowed) in Switzerland, put together by the UniZH.
Here is what is said about Bacitracin: http://www.vetpharm.uzh.ch/wir/00000140/5874__F.htm
Read especially the Indikation, Kontraindikation, Unerwunschte Wirkung and Toxizität bits.
It's also a good idea to speak to your vet about putting together a first-aid kit; get his/her recommendations as to which OTC meds are appropropriate for your dog. The contents of such a kit will vary according to the individual, but some general tips can be found here: https://www.avma.org/public/Emergenc...et-Owners.aspx
Many vets or Hundeschule offer first aid seminars - highly recommended.
Hope your doglet's cut heals quickly.
