Some bleed a lot, some just drops; most clean up after themselves to a greater or lesser extent.
I have had females so self-cleaning you had to look twice daily and swab to even hope to find them ‘bleeding’.
Please realize most females will breed AFTER the bleeding changes to near clear or ‘nope, not bleeding’. Be watchful for at least 21 days from today - mark the calendar.
Mesalliances can happen unbelievably fast if there are males in the vicinity: females in heat stay on leash every time they go outside during the time.
Other than that, intact females are easy to deal with. Never had problems in 30 years of owning hounds and herding dogs.
Terriers and solo workers can have a different mindset regarding more than one female in a household, so I’m not projecting my get-along gals to another person’s situation.
If intact females were not more prone to eventual breast cancers and pyometra, I would not neuter, but then, my situation is different than most busy families or non-dog crazy individuals.
