"Busy homes, colder weather, and celebrations bring a whole new set of risks for pets. Dr. LoSasso shares what to watch for as temperatures drop and holiday traffic picks up."— Julie Schwenzer
Episode summary
Part two of the holiday hazards series shifts from things pets might eat to things that happen when houses fill up with people and unfamiliar animals. Dr. LoSasso's first flag is bringing pets into someone else's home, or hosting someone else's pet in yours. Mixing unfamiliar dogs changes pack dynamics — suddenly there's competition over treats, attention, or a shared bowl that wasn't there before, and two dogs that seem perfectly fine together can have a sudden fight without warning.
"They get along just fine — and they might, until the day they don't. I'm not bringing another dog in with my pit bull. She's a sweet, amazing dog, but I don't know what she's like with these others, so it's not something I would voluntarily introduce."— Dr. Michael LoSasso, DVM
On plants, he's happy to bust a long-running myth. Poinsettias have carried a "deadly toxin" reputation for over a century, traced back to an early-1900s death that had nothing to do with the plant — pure correlation mistaken for causation. In reality, poinsettias cause the same mild stomach upset most houseplants can, nothing more; the actual risk is a rambunctious puppy knocking one over. True lilies are the real danger — genuinely toxic to cats, to the point that Dr. LoSasso says a household with cats should simply never have one in the house, though this is more of an Easter/spring hazard than a Christmas one. Dieffenbachia and snake plants (mother-in-law's tongue) can cause oral irritation. And while oleander (common in Texas landscaping) and foxglove (more of a northern plant) both contain cardiac glycosides capable of stopping a heart, he notes dogs and cats rarely go after either one in practice.
Dr. LoSasso has never personally treated a case of frostbite — North Texas doesn't get cold enough for long enough. When frostbite does happen anywhere, thin-coated dogs with poorly insulated ears, tails, mouths, and feet are most vulnerable. The regional risk here is different: ice storms and freezing rain rather than snow, leaving yards extremely slick — he's seen more than one dog slide on ice straight into a swimming pool. Wet fur dramatically reduces insulation and speeds up hypothermia, which he's seen most severely in older dogs. In colder climates, walking onto a frozen pond or falling through ice into a stream is the real hypothermia risk, and those pets need to be warmed up promptly.
He closes on overstimulation. Stress colitis — significant, sometimes bloody diarrhea brought on purely by anxiety — shows up often in older dogs unused to a house suddenly full of loud young grandkids, or in resident pets stressed by an unfamiliar visiting dog. His practical advice is really about courtesy: think twice before bringing a pet somewhere it isn't the norm, and recognize that a relative bringing their own dog adds real stress to yours, even when everyone insists "they'll be fine." Sometimes they are — and sometimes you end up at the emergency hospital with fight wounds over something as small as sharing a food bowl.
