This is one of the many articles out there connecting human hyperactivity and oxygen deprivation prenatally and postnatally.

There's lots of info linking hyperactivity with O2 deprivation, just Google. Not much research done on dogs, but a ton on children, it very likely applies to dogs also.
Do not equate a human with a canine neonate. I have taken as much as 30 minutes to revive a newborn puppy, and they turned out just fine--in fact, especially fine. They met all their developmental milestones on time, didn't develop seizures or behavior problems, sailed through obedience training, and were lovely family pets. In one case, a great show dog.
Stop looking for reasons and look for solutions--a new dog trainer, a new allergist, and perhaps a new owner.
I too had a girl who wore her front teeth down to nothing in the course of a year. They didn't have to be pulled, she had nothing left.
Allergies can be 1 of the worst problems. This was a 1st for me and I hope I never see it again. My girl was on all types of medications from steroids to a medication that cost my pharmacist $225 a month his cost which he relayed to me. I spent over $5,000 in specialist bills plus medications, medicated shampoos and food changes with no relief. At age 8, I had to put her out of her misery. It was heart breaking to find her ripping herself apart until she bled by 5 in the morning daily.
Her grandsire on the stud side was known for many of his get having allergies and other illnesses. He was also in the bitch side of the pedigree 6 generations back. There was too much of him in both pedigrees.
I never bred her Mom again once her daughter's allergies surfaced at age 3 suddenly. She had a full sibling from a 2nd litter. I bred to the same stud before knowing what he was known to produce. This girl had other serious health problems which iced the cake. I spayed my CH girl, who was finished at 16 months with minimal showing, all majors. She also had her JH, CGC & TDI.
Allergies can be lethal. I never saw it before in 20 years in Labs and another breed. Most are environmental but I tried all different expensive foods just in case including 2 different grain-less foods that were expensive. Nothing helped, food or 6 different medications prescribed by the dermatology specialist.
I understand some of what you're going through & hope you find a better solution then I did. I can't suggest anything because nothing helped.
We just came from the vet Temaril P 100 pills $85 plus the office visit. The vet said 3 pills in the am and 3 in pm. My husband took her as I was working. There isn't a schedule for reducing the pills.
Hoping for a miracle.
Thank you everyone! This is why I love this forum.
Thanks I'll do that. I was so happy to get them....I worry they are mad at me. Maybe you remember I posted on here a little while ago about my girl who they wouldn't let go home after minor surgery on a Friday. Kept her all night in the "hospital" with no one there. I am treading softly...
My vet dermatologist told me that there is a new allergy drug being released this fall and she expects to have it by November. My 9-year-old allergy boy is on her list to receive it. She thinks most vet practices will be able to get the drug by the new year. She was very excited by it. You might want to alert your vet.
I understand your frustrations regarding the allergies. We have spent a fortune keeping our boy as comfortable as we can. He gets allergy shots every 10 days, and is currently on Temeril P every other day until the cold weather arrives.
