It is said any fruit with large pit is a danger for the horse...the pit shell is toxic aside from not digestible.
Plum, peach, nectarine, apples seeds if enough ingested contain cyanide and apples ferment where they should not again in large enough quantity causes issues...
is another warned against them consuming. Ivermectin
syringe empty containers from horse wormer is often deadly not because of the Ivermectin but because of the strength of the product geared for a horse, even in small amounts is to strong and kills.
Cap the container and literally throw it in a sealed garbage can for disposal. Advil, Tylenol or the generics
can cause great distress and poison dogs...
Aspirin in proper dose is safe to administer. I know you were looking for dangerous, but safe to have on hand/use I think is good to know in case of emergency too... Benedryl
is safe in appropriate dosage for a dog suffering from a allergic reaction as you seek medical help. Bring the container with you and know how much you gave for the vet to know... Benedryl
also can help to calm a distressed animal from say fireworks if you not have vet prescribed tranqs to give.
I've also used Benadryl for my dog when he broke through his seizure medications....was not pretty.
My vet told me expired Banamine
as long as it is not cloudy is safe to administer.
Up to 3 years post expiration they have known given with no adverse effects...
If anything a bit less potent, but the secret is it must be clear solution not cloudy otherwise dispose of it safely.
I always use expired Bute
tablets and never a issue with that one either...3 years is a max and then trash can here it comes.
I use so little of either above products my neighbor and I now purchase together...between the 2 of us and 8 horses we still throw out a lot of unused.
that's a good thing actually. If anyone knows any different on expired meds mentioned please speak up... ...
