Poor sweetheart!
I'd recommend a cream-based topical antibiotic (something like thermazine or silver sulfadiazene) instead of an ointment. Ointments are greasy and can cause a buildup of debris to the wound.
That second photo looks like the wound could use suturing (even really crude sewing together, if you're handy with a needle), but she could also benefit from a wet-to-dry bandage if you're not comfy with a needle.
Wet to dry is gauze plus warm saline (or chlorhex, but NOT peroxide) on the wound, dry gauze (thick) over the wet gauze, coflex (or tape?) to hold it all in place.
The wet gauze keeps the exposed underlying tissue from drying out, and stops the wound from healing over and essentially creating a closed abscess (akin to dry rot in a mouth); it lets the would heal from the inside out. The dry gauze keeps it from getting too moist in there. So you'd apply antibiotic cream, then the wet gauze, then the dry
change every 12-24 hours, cleansing away (gently) the old antibiotic when you do.
I would also like to x1000 the suggestion to increase her temperature; it bolsters the immune system. Putting her under a low wattage heat bulb should do.
She'll be in my thoughts!
