Keep her, at the very least give her a couple of weeks to see if Franklin can adjust and get used to her. He will, very likely, come to enjoy and like being with the new pup.

But, otoh, I have not had to deal with the seizures. If they continue then I don't see how that can be fair to Franklin since, afterall, he was there first.

And all of this makes me nervous about us getting a pal dog for Nande when we get back from our trip. But I think the circumstances and personalities are a bit different (i.e. Nande craves play and a dog that will play is already her best friend).

Either way, its a tough call but I would lean toward keeping the pup and seeing if things don't improve.

I'd vote for keep her, at least for a while. Dogs are resilient... they adjust.

Here's an update:
Franklin is back from the vet. The reviews are still pending the complete lab results. We are honestly hoping for thyroid problems, as that would be the easiest to remedy. Those symptoms range from seemingly dumb behavior, regularly loose stool, loss of appetite, awkwardness...he's got them all.

Right now, they have him on a high does of Phenobarb. From what I've read it's not the best long-term solution. And, he's kinda not the same-glassey eyed, and giddey, but sleepy at the same time. Potassium Bromide seems to be a better alternative. But that has to be prescribed by a neurologist, which sounds cheap. And, I don't know about you, but when I hear bromide I tend to thnk of two things:

1. Old-man Teddy Roosevelt nursing his safari-weary bag of bones in a Turkish salt bath, sipping the latest concoction;
2. Helen Keller knocking back her meds at the asylum.

We sleep with a valium syringe next to the bed. Which my wife gets to stick in his thigh if he seizes again. Also, as we read, not the most effective application. We'd much prefer that rectal-valium applicator. It gives us another use for the bottle of KY that sits next to the bed.

We're keeping the pup, who has us playing a nice game of couch, furniture, couch, plant, shoe, couch, table, furniture, couch, couch, couch, couch...weee. She has me and my wife trained to put away...everything.

The shitty part is that we are faced with having a dog that may not be all that healthy, and as things turn out, alot older than we originally thought. Franklin is more likely 6-7 yrs. and not the 4 we thought him to be. Right now, we are think pup or no pup, he probably would have exhibited this behavior anyway. The fact that the seizures are exactly five hours apart, like clockwork, lead me to think that there is something chemical going on. That, and he's never had any episodes with any of the other dogs or places he's been left at while we travel, weeks at a time.

Keep in mind that dawgs are very territorial and the stress of having a new critter in 'his' den is way more than any off-site visit can ever be (except for maybe a kennel). That and all the attention to the new one will definitely make him consider his alpha status, so the poor pup is probably suffering from an identity crisis.

Also, are you still feeding him modified people food? There may be a nutritional deficit in there somewhere that may be contributing to the chemical imbalance.

Or maybe he's faking it for attention. He hasn't started cutting yet, has he?

That's the only thing jen and I can think is the difference. We never would have thought that a new pup in Franklin'n den would have resulted in grand-mals. As for the diet, we totally stand by it. He gets a part raw, part kible diet that has kept his teeth and ears totally clean. We used tp pull black gunk out his ears every other day. Now they are spotless.

Either way, it doesn't matter. The hound is going back this evening. And Franklin is headed to the nuerologist on Wednesday. We're sad about the whole thing, but on the dissapointment scale, we're not going to let this get exagerated.
