When introducing this weed for the first time, you need to begin with small amounts and you study how their stomachs are going to react. Afterward, increase the amount slowly over a period of about a week.
On the amounts to give them, a chopped cup of 4-5 leafy greens including dandelions is enough for a rabbit weighing two pounds a day. There are many greens you can go for including arugula, carrot tops, kales, lettuce, turnips, mint, basil, dill leaves, raspberry leaves, cilantro, and so on.
Also, keep varying the various leafy greens you give your pet since there is a long list of the various types they can eat. Avoid or occasionally include only one type of leafy greens with high oxalic acid amounts such as parsley, spinach, mustard greens, beet greens, radish tops, and so on.
Remember leafy greens and treats (fruits and non-leafy vegetables) should account for only 10-15% of your rabbit's diet the rest being hay (over 80%) and about 5% high-quality pellets. Do not forget an unlimited supply of clean, freshwater.
If you need hay, go for brands like Small Pet Select 2nd Cutting "Perfect Blend" Timothy Hay Pet Food, Kaytee Timothy Hay, Standlee Premium Western Forage Timothy Grass, among others while Kaytee Supreme Food for Rabbit, Oxbow Animal Health Bunny Basics Essentials Adult Rabbit Pet Food and Small Pet Select Rabbit Food Pellets are good brands of pellets.
Finally, excessive amounts of any leafy greens may cause diarrhea, gas, bloating and other stomach upsets. Always stick to the recommended bunny diet to avoid such problems.
