Hello, my name is***** and I have over 20 years of experience as a veterinarian. I am sorry to hear that your pup may have ingested your husband's silk eye shades.
I understand that he has a history of eating things he should not and successfully passing them.
The two concerns here would be if the shades got wadded up it could cause a blockage and if part of the shades got caught and the cloth became unraveled the strings can act like a hacksaw on the intestine walls.
These may pass, as things have before, but if has been less than 2-3 hours since he ate them it may be worth trying to induce vomiting to get them out before they cause any trouble.
You can give him 1 tablespoon of 3% hydrogen peroxide per 10 pounds of body weight soaked up with bread chunks, or mixed with ice cream or a little food (no more than 3 tablespoons at a time even for a pup greater than 35 pounds).
Then take him outside and run him around to get the peroxide bubbling so he vomits.
If no vomiting in 10 minutes repeat the peroxide dose once.
If he vomits and seems to clear his stomach and be done I would check to see if the shades are present.
Once he clears his stomach to try and settle his stomach today you can give either:
1) Pepcid-ac (famotidine) at a dose of one 10mg tablet per 20 to 40 pounds of body weight every 12 hours.
2) Prilosec (omeprazole) at a dose of one 20mg tablet per 40 to 80 pounds of body weight every 24 hours.
These will reduce stomach acid and should help settle his stomach.
Then feed a homemade diet of 1/3 boiled, lean hamburger or boiled, white, skinless chicken, all fats and juices drained off the meat, and 2/3 white rice. Add 2 tablespoons of canned pumpkin, (not pie filling, just pumpkin), to each meal for fiber whether he vomits the foreign material or not to help push any remaining pieces through.
If it has been less than 3 hours and you don't have peroxide or he doesn't vomit you can get him to an emergency clinic to induce vomiting.
If it has been longer than 3 hours it is likely too late to induce vomiting, then just feed him the high fiber bland diet mix and watch him for signs of irritation or a blockage.
If he starts vomiting in the next few days, has a tense painful belly or refuses to eat or runs a fever (more than 103F rectally) then that can signify a blockage and he should be seen by a veterinarian immediately. Surgery may be needed at that point.
Please let me know if you have any further questions.
