My most recemt purchases of combs and a brush have been from topoflinepet.com as well. They are good quality and great prices. I purchased the small Maden brush and though I would like an even smaller brush this one works fine. I have the 4" comb for her face, head and legs and use a 6" comb for her body. I use combs more than anything else. I usually finish with the brush. Her fur is silky so I don't deal with a lot of tangles except in the ends occasionally. I find the comb works best for dealing with that.

There are as many opinions about food as there are owners. Personally, I feel that the closer you can move to what a dog would naturally eat the better off your pet would be, especially as it ages. Many of the grocery store or department store pet foods are very cheaply made with poor quality of ingredients. Some pet owners have gone to grain free and have had good results. Some feed raw while others swear by traditional foods. I would advise you to read up on foods and study ingredient lists and decide what is most important to you. Some people go to :
Dog Food Reviews | Dog Food Ratings
It does have a lot of information about ingredients that are in pet foods. I figure that if you cannot pronounce or even identify some of the ingredients on the bag of food it may be time to find out what your pet is actually eating.
