She's very young. It does take some bitches a couple of years (cycles) before they settle into a routine - which is another reason not to neuter them until everything has really settled down !) I wouldn't worry too much, just keep a close eye on her.
She was born 'out of season' - but will probably revert to one proper season a year in time.
@donc - Age to compete for AKC and ASFA lure trials is 12 months of age
Thanks. Seems odd to me to have the same minimum age for Fast Cat and Lure Coursing. The latter will put a lot more stress on the dog than the former. Then again, large dogs and small dogs are not the same, so having a good age requirement would be difficult to come up with.
I would be careful with tea tree oil based shampoos, essential oils it can trigger seizures in dogs who have history of epilepsy. It happened to one of mine, when we put teatree oil on him as a flea preventitive.
@jengosmonkey - NuHeart only does Heartworm, Heartguard Plus has meds for roundworms & hookworm. And people that give heartworm for 6 months are typically people that live in climates that have a cold winter, ie: when the ground freezes. We do not have that in this part of No. California so I give it year round.
