We have both - front and rear - buy because our old Hovavarth Sheepdog mixed breed (just under 13 years old) is too hard for me (30 kg), to carry him up the stairs. Even while walking it is a great help, because otherwise the dog back buckles and also when you get up.
The baby carriers from Pfaff are very good of the fit and finish.
Our dog fits both in XL - size, we were able, thanks to the chart that is stored in Amazon, choose right the first time. First, the baby carriers are sitting tight, however, provide them with the time a little after, so that they are not too small but just a little and be more, which makes them fit more easily.
As a woman I can our "giant" with two baby carriers alone high carry the stairs, partially runs with times, often he can also just hang in the bags.
Even individually, we use the baby carriers - the front, for example to get up from the dog mattress when the hind legs do not want it but then can go on alone.
Or to go down on the stairs, when he has a good day and the back is not equal to buckle.
Otherwise we just take both aids front and rear, if the legs do not want to, depending on its form on the day.
Anyway, to get with the Pfaff Babywearing very well up the stairs and down, can place the dog and help him go.
A huge help that is! I do not know what I would do without these tote bags. Thanks to Mr. Pfaff!
They are also anatomically correct (our male may settle urine and feces - very important in sick old dog !!!) and save the dog (no pressure on the leg or scraping of the skin).
The baby carriers are stable, but softened by neoprene, while the straps stabilize the neoprene. It has a secure feeling when you thus bears his favorite and he leaves it up like fallen (of course you have patience and love to practice).
That the handles adjustable in length and also from soft neoprene are, is very helpful for people not too large (1.68 cm), because otherwise I can not lift the dog. I need short handles and which is at the Pfaff Tragehilfe front and rear fortunately easy to adjust!
These are definitely the perfect wearing aids for elderly, disabled, large dogs, we can at any rate contribute from our experience.
We would recommend this Pfaff Premium Carrying Aids definitely!
