Trees
"An apple a day keeps the doctor away"?
Our faith in this maxim is not shaken by the well-known fact
that apple seeds contain cyanide. Nor should it be.
But according to the ASPCA, even the leaves of apple trees (Malus) are toxic,
and The Merck Veterinary Manual confirms this claim.
Since the hawthorns are related to apples, it should come as no surprise that
Washington hawthorn trees (Crataegus phaenopyrum) are poisonous to canines.
More examples:
- Oleander (Nerium oleander)
- American holly (Ilex opaca)
- Yellow bird of paradise (Caesalpinia gilliesii)
- Golden chain (Laburnum × watereri)
- Oak trees (Quercus; leaves and acorns poisonous to dogs)
Bulb Plants
You may have heard that squirrels(a major pest for many other
spring-flowering bulb plants) will not eat daffodils.
But do you know why? The fact is, daffodils (Narcissus) are toxic.
Other bulbs toxic to dogs include:
樹木
一天一蘋果遠離醫生?!
即使我們以了解蘋果的種子含有氰化物,但我們依然對此諺語衛有懷疑的念頭.
真不該是如此.但是根據美國愛護動物協會表示,蘋果的葉子也是有毒的,
就連Merck Veterinary Manual此書也表示認同此聲明.
如此一來和蘋果有關係的山楂甚至是華盛頓霍桑都也是對犬類有毒的.
更多例子如下:
- 夾竹桃(Nerium oleander)
- 美國冬青(Ilex opaca)
- 蝴蝶花 (金鳳花) (Caesalpinia gilliesii)
- 金鏈樹(Laburnum × watereri)
- 夏櫟(Quercus; leaves and acorns poisonous to dogs)
球莖植物
你可能聽說過松鼠不會吃水仙花的球莖(松鼠是春天開花的球莖植物的害蟲)
但是你知道為什麼嗎?因為水仙花的球莖有毒.
下列的球莖也有毒:
- 風信子(Hyacinthus orientalis)
- 鬱金香(Tulipa)
- 百合(Lilium)
- 蔥
