Do you know what could poison your pet?

Every so often a case comes into work that prompts me to write a blog post about it.  This time I decided to write about poisonous things that you may or may not know are poisonous, either in your house or when you're out walking the dog.

I used the BSAVA/VPIS Guide to Common Canine and Feline Poisons to help me.  It was put together by the BSAVA and the VPIS to aid Veterinary practices.  We can contact the VPIS at any time for advice on a case but they decided to put this book together using their most common cases.

Obviously, this list is very limited.  There are a great many poisonous things out there, and I've chosen to only list a few drugs but, generally speaking, if you're pet eats any of your medication you should contact your Vet as soon as possible.  Not every medication is bad but most of them can lead to problems, especially if ingested in excess.

I've also not listed any actual poisons, for example slug and rat bait, weed and plant killer.  I felt those were kind of obvious but in case they're not ...... THEY'RE POISONOUS!  If your pet ingests any of them or gets them on their coat, contact your Vet as soon as possible.

Another one I've not listed but is common, especially in the winter, is Ethylene Glycol (Antifreeze), it is sweet tasting so pets want to lick it and it is EXTREMELY toxic to them.

As I said, this list is limited, I've tried to keep it to common and/or household toxins.  I'll be listing the onset times of clinical signs as well as what the clinical signs are.  In those lists there may be some words you don't know, I have made a list at the end of any words I think readers may have trouble with.  If there's a word you don't know and I haven't listed it at the end, let me know in the comments.

So on with the list, to keep it simple I'll be using the alphabet as my guide.

Heatstroke in Dogs

Hyperthermia is an elevation of body temperature out with the normal range.
Heatstroke is a form of hyperthermia (non-fever) that usually occurs in the hotter weather but it can happen at any time.

There are some predispositions to heatstroke:

  • Brachycephalic (short nosed, flat faced) breeds like pugs, shih tzus, bulldogs, boston terriers etc. are more at risk than other dogs purely due to the shape of their face making breathing more difficult
  • Very young or very old dogs
  • Obesity
  • Heart and lung disease
  • Dogs with a thick, heavy coat
  • Dehydration
All of the above have an increased risk of developing heatstroke.

Things that can cause heatstroke:
  • Excessive heat - may be due to weather conditions or being shut in an unventilated area
  • Being left outdoors in hot weather without adequate shade and/or water source
Symptoms of heatstroke:
  • Panting
  • Excessive salivation
  • Red gums
  • Thick saliva
  • Muscle tremors
  • Weakness
  • Ataxia (uncoordinated gait)
  • Vomiting
  • Shock
  • Coma
What to do if you suspect your dog has heatstroke:
  • Contact your Vet ASAP, your dog will need to be seen
  • Cool your dog down in transit, don't use ice or ice cold water.  Wet some towels and cover your dog with them, put a fan on them
  • Don't force water into their mouth but have drinking water available in case they want a drink
Prevention is better than cure:
  • Don't leave your dog in a car - doesn't matter what time of year it is, dogs pant and they can cause a car to heat up real quick
  • Don't exercise your dog when it's warm outside.  My own gets walked in the morning when it's cool and then she doesn't get walked again until later in the evening - toilet breaks only during the day
  • Make sure your dog has plenty of drinking water
  • If your dog is in your garden, make sure they have the ability to get back inside or some form of shelter
This is just some basic info I wanted to put out there as we usually see a lot of dogs in work with Heatstroke at this time of year.

Breedism

Today I'd like to talk about breedism. It's something that I always see in the media, and it's something that never fails to get me riled up.



The above types of dog, if involved in an incident, are described as being "devil dogs". Especially Rottweilers and Staffordshire Bull Terriers.
I have worked with animals for about 10 years now and, of the above types of dog, I rarely see aggressive ones. For each type, I could count on one hand how many aggressive dogs I have seen. The problem with these dogs are the types of people that buy them. A lot of idiots that think they're "hard" will buy these breeds as a status symbol. Then they don't train them right, or purposefully train them to be aggressive to make seem even "harder".
When truthfully, they're actually just complete dicks that are doing more harm than good.
I'm always reading letters, or such like, from parents and other dog owners saying these dogs should be banned, should all be muzzled etc. Again, the people that write these letters know nothing of what they're writing about.


Now, every Vet Nurse I know, has a breed that they have had run ins with in the past and are wary of. That's not to say we think they're all aggressive and must all be muzzled, my breed?



West Highland White Terriers





Most that I meet in practice are snappy. But I'm not running around saying all Westies should be banned and muzzled, calling them "devil dogs". I'm just more wary around them than other breeds. Although with the small aggressive dogs, I think it's because they're spoiled when they're pups and then, when they're older, it's too late to do anything about it.


So, my biggest bugbear is with the media always blowing these things out of proportion, and idiots buying dogs they know nothing about. So, if you're going to buy a dog? Research the breed first. Take it's training seriously. And socialise from a young age. If every dog owner did thise, we'd see less "devil dog" stories in the media.


To finish this off, here's some cute pictures of some cute puppies. And the classic "staffie smile".

Christmas Hazards for Pets

Yup, it's that dreaded time of year again. Christmas.

I'm a total bah humbug person but, given my day job, I thought I'd write a post about the hazards of christmas to your pet.

Christmas Trees
Yes, the simple christmas tree ... can very easily be pulled down by a curious cat or a hyperactive dog. Please make sure your tree is secured or cordoned off so your playful puppy or climbing kitty cannot be harmed. Also, if you have a real tree, make sure you clean the pine needles up regularly. They're not overly dangerous but they could stick in delicate unshod little paws and would be very uncomfortable.

Lights
Again, very easy for a cat or dog to get tangled in them or chew on them. Make sure they are attached securely and try and cover the cables so they can't be spied by curious eyes.

Tinsel & Ribbon
This stuff can be very dangerous if swallowed. If you're pet is lucky, it could just pass out with no damage. The unlucky ones could end up needing surgery to remove the offending article and also some damaged bowels. Keep everything out of the way from your pets.

Baubles
Anyone that's ever dropped one of these while decorating know how easily they shatter. Just be careful with glass baubles if you have a pet, try and not give your pet the chance to knock any off the tree.

Holly
Holly leaves and berries can be toxic to pets and will cause some gastric upset. Best not to give your pet the chance to eat any.

Mistletoe
Mistletoe, same as holly, can cause some gastric upset and it can also cause some heart problems. So, again, better to not give your pets the chance to eat any.

Ponsietta
While not toxic to pets, it can cause some irritation of the mouth, as well as excess salivation and possibly some vomiting. Again, as with most of the things on here, try and avoid your pet getting a hold of it.

Lilies
A relatively new turn up in the Veterinary field, lilies are extremely toxic to cats. A simple brush up against it leaving pollen on the cat's coat can cause kidney failure. Not just a christmas thing but a lot of flower arrangements will have lilies in them. If you are a cat owner, you should try and avoid lilies completely.

Batteries
Again, not primarily a christmas thing but it is a time of year where people tend to have a lot of batteries around for toys and decorations. Obviously batteries, if chewed, can cause a lot of damage so make sure batteries are well hidden from your pets.

Chocolate
Most people know about this by now but I thought I'd put it in here anyway. Chocolate contains a chemical called Theobromine which is toxic to pets. The general rule is: the darker the chocolate, the more theobromine so the less is needed to be toxic. Try and keep all chocolate away from pets, so don't place chocolate beneath the tree and try not to use chocolate hanging decorations.

Raisins, Grapes & Currants
Not as many people know about this, but grapes, raisins & currants can cause kidney failure in dogs if ingested. Again, the best course is to make sure your dog can't access these.

Turkey BONES
No, turkey's aren't toxic to pets but the bones can cause a lot of damage if ingested. Bird bones are hollow and shatter very easily so if a dog or cat swallows a bone, they can cause a lot of damage to their digestive tract. They can scratch and cut on there way down and could puncture through the intestines, this would require fairly major surgery. So it's just better to make sure your turkey carcass is disposed of properly and don't give your pets a chance to get at it.

Another thing to remember at this time of year is a chemical called Xylitol. It's an artificial sweetener and can be found in a lot of chewing gums and diet sweets. This is, again, fairly new to us in the Veterinary world but it can cause a lot of problems if ingested. And it doesn't need to be a lot. So, like everything else, try and make sure your pet doesn't get a chance to eat it.


When you look at this list, it seems like christmas is a very dangerous time of year, but if you think of all these things as you're decorating and "hiding" (not always from pets) presents, you'll hopefully be hazard free.
