Oh yeah, you're right, my bad. However, Sentinel does kill roundworm, and Strongyloides is a roundworm.

From the Merck Veterinary Manual: Ivermectin, selamectin, moxidectin, and milbemycin oxime may be used in dogs for the prevention of heartworm disease and control of GI roundworms. Many canine parasites are susceptible to ivermectin at the dosages used in other animals; however, because some dogs are adversely affected at these levels, ivermectin is used in dogs at only 6 µg/kg body wt, given at 1-mo intervals, to prevent development of Dirofilaria immitis , the cause of heartworm disease. At higher dosages (>100 µg/kg), some Collies are adversely affected by ivermectin. At a dosage of 0.5 mg/kg, PO, milbemycin oxime is used for prevention of heartworm infection and for treatment of hookworms, ascarids, and whipworms in dogs. Moxidectin is also effective for the prevention of heartworm infection at a dose rate of 3 µg/kg. The margin of safety of milbemycin and moxidectin in dogs, including those sensitive to ivermectin, appears to be similar to that of ivermectin.

Ascarids are roundworms (which is what Strongyloides are, a type of roundworm), so her vet did give her very good advice.

When I first got my pup, I immediately took her into the vet and they found she had tapeworm. One shot, and all fixed up. Strongyloides is very curable too in the early stages. What with all of the big problems a Yorkie can have (luxating patella, liver shunt, AAI, etc), this is not something to send a pup back to the breeder for. It's a problem easily solved.

What you bolded does not apply. Strongyloides are not hookworms, ascarids or whipworms. I have already supplied a link to Merck Veterinary Manual regarding the treatment of strongyloides. Merck Veterinary Manual

Tapeworms are also a different type of worm.

Here are more sites w info of treatment of strongyloides. Veterinary parasitology reference manual - William J. Foreyt, Bill Foreyt - Google Books

Intestinal Parasites In Your Dog And What To Do About Them

As I said before, she really should be speaking w a DVM about this, not us. I am a member of Mensa and have degrees in medical/biological sciences; however, I am not a DVM.

I do believe the breeder should be contacted, as her vet has done, bc this was probably contracted/infected on her premises and also a health guarantee might be in effect to help her offset her vet costs.

Stongyloids are a type of roundworms. Source: Roundworms (Nematodes) | Natural Health Techniques

It's right under the "warning" about the gross pictures.

If Sentinel is is touted in the literature as effective in treating roundworms (that's what I use, and it is on the box and in the literature inside the box), then would that not incude ALL types of roundworm? It doesn't say it is effective against roundworm, except for Stongyloids ... it says that Sentinel is effective against roundworms. Period.

For the sake of clarification, because you seemed to miss my points:

1. I never tried to give her veterinary advise. I merely tried to put her mind at ease by pointing out sources that backed up what her vet was telling her. IOW, your vet has given you good advice, just follow it.

2. I never implied, directly or indirectly, that tapeworms are the same. I was merely pointing out, in the grand scheme of things, there are some things that are very serious, expensive, and difficult to fix. In contrast, worms are inexpensive, easy, and quick to fix. Just another thing to try and calm her fears about her pup.

And yes, the breeder should certainly be told about the problem so that they can fix it on their end, because the OP hasn't had the pup long enough for the infestation to happen on her end.

We have some things in common! I have degrees in chemistry and biochemistry. Although I never bothered to look into Mensa, I don't know what it proves so I thought it would be a waste of time.

I do hope the OP feels better about her situation and can trust her vet. Although I'm wondering, what with the Sentinel shortage, if they'll be able to get it, but then they could always rely on one of the other treatments.

I am really starting to see why exp breeders no longer post here. I've tried to be polite, as you started your posts by giving misinformation about the active ingredient in Sentinel.

I've seen exp breeders argued w when they recommended goat's milk. I've seen an exp OR nurse who works w breast cancer pts argued w when trying to give help to a breast cancer pt. Amazing.

I think the threads I've provided are self-explanatory. She really needs to discuss her pet w her vet as he was able to examine the pt and the stool. If she questions the validity of a substitute for ivermectin, I think it is a good question to address w a DVM.

Mensa is an organization for ppl w the top 2% of the populus in IQ. That is the prequalifier for entrance into the organization. I'm sure the other members will not care that you find their prestigious organization a "waste of time".

I hope the OP is still reading. Everything I stated was in response to her concerns ... she wanted to know if the dog would be sick for it's lifetime, should she take it back to the breeder, would there be high vet bills. She needs to be reassured that this will be easy to overcome, and that her vet has given her good advice ... and that is all that my responses ever did. No need to take her pup back.

Again, Sentinal is for heartworm, whipworm, hookworm, roundworm (and fleas). Roundworms (Also known as Nematodes) includes Ascarids, Hookworms, Stongyloids, Heartworms, and Whipworms. If Sentinel kills roundworms, and a Strongyloid is a roundworm, then Sentinel will kill stongyloids. This can be easily treated and fixed. Next step is to discuss further with her vet and start treatment!

This has really gotten old for me (and probably for the OP and other readers).

Like I said before and will say again, the links I provided speak for themselves about treatment/diagnosis.

Actually, being a member of Mensa helps you get into better schools and does get you better jobs/salaries/fellowships and helps weigh into acceptance into graduate and post-graduate work. I guess you must have misinformation about this subject also. Perhaps you know that old saying, "What do you call a man who graduated last in his class in medical school - Dr." We tend to have better class rank. Who do you want working on you?

I stumbled across this. Op get the problem fixed?? I know someone who had this. Easy fix with a pup. 3 day treatment of Fenbendazole. Unless it's a bitch in chronic in the tissues. stages it maybe hard to get rid of from what I read. Dunno but they were worried because it's rare in my area

If the vet can prescribe the correct medicine or recommend someone who can. You need a new vet. Most ppl can use Google and find better than that??:(

Did the OP speak to her vet? looking for updates.....

Just checked the dates..this thread is from February!

I know. Kinda old but I brought it back up. This thread worm can be mis diagnosed. I've seen it happen. And can be cured easy if detected. When it gets in the skin. It can be a different story. Rare in the North more common in Southern hot states
