Just planted by professional landscaper in front garden. We need to know required maintenance.
It is important to know the variety that you have planted for the correct care and trimming instructions.

I live in SE Oklahoma and Sumac bushes are overly abundant. They are very pretty, and I am wondering if they are poisonous; either to dogs/cats or humans?
The ASPCA maintains a database of poisonous plants. Here is the link: https://www.aspca.org/pet-care/animal-poison-control/toxic-and-non-toxic-plants
There are several varieties of sumac with "poison sumac", Toxicodendron vernix, capable of causing poison ivy-type rash. However, it is not known to inhabit Oklahoma and is only found where it is very wet, like a swamp. Check with your vet about dogs/cats. The following website has pictures of the other, more common, sumacs, staghorn and winged. Knowing which variety you have will help answer your question. http://www.poison-ivy.org/poison-sumac

I was given a free tree from the free tree program . They showed us how to plant and add mulch, and how to water. It has been 2 weeks and the tree still looks the same. What I need to know is when should I see something. The tree is Staghorn Sumac. Thank You
Give it more time. Follow the directions you were given about watering. A newly planted tree can take a month or more to establish and start to put out new roots and foliage. If you live in a temperate climate this may not happen until the spring weather starts to warm up and the spring flush of growth gets going.
Now that the snow has gone, I noticed that the rabbits have been eating the 3 branches of my Sumac tree over the winter (second winter of the tree). One of the branches broke off (dead). Will the entire tree be dead?.
To be fair, mice tunnel under snow and chew on bark so the bunny may have had help. The extent of bark loss is crucial. If it encircles the base, nutrients can't flow from the roots to the leaves to allow leafing out. However, you are likely to get another sprout from the roots. That new growth will be nice and juicy to the rabbits.
This has started growing in my garden about a month or two ago and it looks quite nice but I'm not sure what it is. Will be most greateful if anyone could identify it please.
It appears to resemble some of the more ornamental sumac shrubs, even down to the red color of dying leaves. I can't be completely sure without flowers, seeds, or other parts to identify the plant.
I am not familiar with the agricultural extension services in your country, but they could most certainly help you identify this species, as they will be more familiar with the plants of your area.
My sumac tree is almost 2 yrs old. the tree has 7 healthy sucklings growing all around her. Can they kill or hurt my tree?
It isn't that they will kill your tree, as much as it will just steal nutrients, and make the tree grow much slower. It is best to remove these. This article will give you more information on the care of these trees: https://www.gardeningknowhow.com/ornamental/trees/sumac/sumac-tree-info.htm
The area I want to grow something in is a small area and I just want some shade on a patio. The Sumac is a good size but I would like something that doesn't split easily, but similar to a Sumac.
There are a number of small tree, large shrub options. Japanese maples are gorgeous specimen plants and come in all shapes, colors, and sizes. The small tree desert willow has a profusion of flowers in the summer. Flowering crabapples stay small and you've probably seen them blooming white, pink or purple-red in spring.
