Of note, I took the kitten to the vet at 11 days, and she tested negative for parasites in stool. I am using the correct formula.

I would say the vet is a very good idea the sooner the better. Every litter I’ve every had from cats to rats to dogs and pigs. The runt rarely survived. But they usually were very sickly from day one. It is possible this little pup is off to a slow start but with a vets help it can be a survivor. Keep it warm and dont let it get picked on by the others. Good luck. 

Thanks I appreciate it she is urinating and deficiating she is also eating as I feed her every 2 hours I then put her back with the rest if the litter and this is when she starts to cry she also is very fidgetated can never stay still

I recommend having a vet do an exam, fecal float (to look for parasites) and possibly x-rays.  Diarrhea for 4 days in a dog this large is not an emergency but he should be seen by a vet soon.

OK this is is what I have done many many times over the years helping friends and family and it works 100% of the time. It takes some time, effort, a little money, and mostly, elbow grease. First thing you need is to purchase some flea killing pills called Capstar. Ebay, or a vets office or online, the animal swallows the pill and 30 min later all fleas are on the ground dead.  Order them today. Then go out and get a good flea med. Some vets won’t give you any if you haven’t been seen by them, so I suggest Frontline from the pet store, use by body weight.  Don’t apply it just yet.  Purchase at least 3 new vaccum filters as the vacuum is your best friend in this scenario.  This requires at minimum a weekend for the initial treatment and then continuing to vacuum daily so suck up any new eggs that hatch. Repeatedly.

Capstar pills, flea meds for each pet, flea bombs for each room of the house except kitchen,  vacuum filters, and most importantly cat carriers or cages or somewhere to place them while this is happening besides the house. 

Now sat morning wake up and get animals out. While they are out give each one a dose of the Capstar pills, a bath,  and then apply the flea med.  Next move all furniture and anything a flea can be under to one side of the rooms and cover with bed sheets.  Next. Vacuum like a crazy person. Twice!  Change the filter and take trash bag with old filter immediately to the outside dump. Vacuum again. Under beds. Under under under.. under couch cushions and anywhere a flea will hide. Closets, etc . Take litter boxes to bathroom and bleach clean. Pick everything up off floors.  Next let the bombs off in center of each room with doors closed and leave the house for alloted time frame.  After that come inside and vacuum good again to suck up all dead fleas.  Now clean off bomb residue off cabinets and stuff and anywhere like tile floors and wipe it all up. Open windows air out a while. Let’s pets back in. Wash sheets covering the furniture.. And put things back. Beside off of floors because you need to vacuum daily for the next 2 weeks.   This will work. It takes effort but will work.  At the 3-4 week mark. I would repeat and bomb again.  At the 4 week mark apply more flea med to animals.   

At some point try to get a better flea med from a vet but for now the frontline will work. Good luck! 

Thank you for your advice, much appreciated! Capstar may work great but, I am not sure how I feel about giving my animals something that they ingest, just seems off putting to me! We vacuum every other day, we have a bagless and wet vac that we use to vacuum our home with. We have no carpet in our home, just hardwood floors so it is a little easier to keep up with. We have tried raid flea spray that you spray around your home, we think it worked a little bit, but where their cat box used to be — we are having no luck there is still load of fleas there. This weekend we are getting the cats flea collars, as much as I don’t want too I think it will work.

Thank you again for your advice!

Ohhh damn, maybe I wont get the collars then. I have tried frontline, it was a waste of money and did not work for us. We vacuum every other day, I will have to try the moth ball thing!

I would keep an eye on it to see if it changes in a few days.  Then I would take him to the vet to get the lump biopsied.

Probably the best thing right now is to make her comfortable until tomorrow. Try to keep her from moving around too much. A crate or dog travel pen is commonly used to avoid moving around. I would place her inside.. right after she uses the bathroom one last time and given some food or water.  Don’t keep touching her where it hurts and don’t fuss over her just keep calm and relaxed.  Good luck.

With out additional info the problem list is long even if you have ruled out infection. Let your vet perform some blood work and other test to reach a diagnosis
